Where you are, and what’s next
Written for C. This is about Mind, People and Body — because that is what you said matters right now.
In your words: “I have been running on empty for about a year. I do not think I need my life rebuilt — I think I need to sleep, and to see people who are not colleagues.”

00 // what this is built on
How change actually works
Most of what gets sold as self-improvement does not survive contact with the evidence. So before anything else, here is what this document is actually built on, and how much weight it can carry.
what the research says
Evidence: moderate· good evidence, some inconsistency
Deciding in advance when and where you'll do something helps — modestly, and mostly when you already want to do it. The popular version of this finding is inflated. Across 642 tests the effect is d = 0.36 before correcting for publication bias and about d = 0.15 after, rising to roughly 0.31 when the intention was already strong. That is small. It is also the reason every step here carries a cue, and the reason we only plan around the parts of your life you told us you actually want to work on — planning at someone who doesn't want to is where the effect goes to die.
what the research says
Evidence: strong· replicated, meta-analysed, or guideline-level
Most interventions stop working the moment they stop. In the largest trial ever run on this question — 61,293 people, 54 programmes — only about 8% produced change still measurable after the programme ended. That is why this plan is small, and why it expects you to come back rather than to finish.
Note · Some things you may have read are not here, on purpose: growth mindset interventions, willpower as a depletable resource, power posing, and “21 days to a habit”. Each failed to replicate. We would rather give you less and have it be true.

what the research says
Evidence: moderate· good evidence, some inconsistency
Mind is where confident advice and thin evidence overlap most. What survives scrutiny is narrow: scheduling something you value instead of waiting to want it, giving worry a fixed appointment rather than arguing with it, and moving the phone rather than trying to concentrate harder. Meditation helps some people modestly with anxiety and low mood and does nothing measurable for attention or sleep, and most of what gets said about screen time and “dopamine detox” is not supported — so it is not here.

- Mentally leaving work alone in off-hours is associated with less exhaustion, better sleep and higher life satisfaction, at small to medium size (Wendsche & Lohmann-Haislah (2017), Frontiers in Psychology 7:2072. 86 publications, 91 independent samples, 38,124 employees.

- The help that works does not require the most senior or most expensive person in the building, which is one reason asking is worth doing early (Richards et al.

after you close the laptop for the day, on three evenings you had already planned to be in
Evidence: moderate· good evidence, some inconsistency
sources
- Writing about something that is bothering you has a real average effect across many trials, and it is small (Frattaroli (2006), Psychological Bulletin 132(6):823–865. Random-effects meta-analysis of 146 randomised studies: average effect r = .075. Two earlier and smaller meta-analyses used fixed-effects models, which limited how far their more encouraging results generalised.)
- In people living with a long-term condition, the unfacilitated version showed no benefit for low mood at all, short or long term (Nyssen et al. (2016), Health Technology Assessment 20(27); 64 studies, 59 randomised. Pooled effect on depression: SMD −0.06 (95% CI −0.29 to 0.17, n = 1,563) short term and −0.04 (95% CI −0.18 to 0.10, n = 778) long term, with no effect on anxiety or biomarkers.)
- Revisiting painful feeling in an unstructured way has been reported as harmful, which is why the timer and the three-session limit are part of the step and not decoration (Littrell (1998), Clinical Psychology Review 18(1):71–102. Review distinguishing time-limited, structured disclosure in ordinarily functioning people, which had good supporting evidence, from open-ended emotional expression in clinical samples, where the process can do harm.)

Put one small thing you used to be glad you had done — a walk to a specific place, half an hour with an instrument, coffee with someone you name — into a specific half-hour, and go whether or not you feel like going.
after the evening you set up the coming week, before anything else claims the slot
Evidence: moderate· good evidence, some inconsistency
sources
- Acting first and letting the mood follow is the best-supported idea in this domain, and it was tested as a structured course rather than as one booked hour (Ekers, Webster, Van Straten, Cuijpers, Richards & Gilbody (2014), PLoS ONE 9(6):e100100. 26 randomised trials, 1,524 participants; behavioural activation vs controls SMD −0.74 (95% CI −0.91 to −0.56). The authors note most included studies were of low quality with short follow-up.)
- In a large randomised trial, scheduling valued activity performed as well as the more complex and more expensive alternative (Richards et al. (2016), Lancet 388(10047):871–880 (COBRA). 440 adults; behavioural activation delivered by junior mental-health workers was non-inferior to cognitive behavioural therapy at 12 months (PHQ-9 mean difference 0.1, 95% CI −1.3 to 1.5).)
- How structured the approach is turns out to matter more than which approach it is, which is the argument for a named activity at a named hour rather than a general intention (Spinhoven et al. (2018), Behaviour Research and Therapy 106:71–85. 36 trials, 3,307 participants; effect on repetitive negative thinking g = 0.48 overall, rising to 0.76 for approaches built specifically around it and 0.57 for standard cognitive behavioural therapy, against 0.14 for a mixed comparison group that included expressive writing, yoga, light therapy and medication.)
BCTTv1 1.4 Action planning
the year
Before the block of work you actually care about, put the phone in another room, close every window that is not the work, and set an end time. One thing until then.
after immediately after you decide what the hardest thing on today's list is
Evidence: reasonable· mechanistically sensible, thinner evidence
sources
- This works by removing the option, not by freeing up mental capacity — the popular claim that a phone on the desk drains your capacity did not generalise when it was tested again (Hartmann, Martarelli, Reber & Rothen (2020), Consciousness and Cognition 86:103033. No overall effect of phone presence on short-term or prospective memory; the only signal was a moderation in participants low in phone dependency.)
- Switching between tasks reliably slows you down and raises errors, and preparing for the switch reduces the cost without removing it (Monsell (2003), Trends in Cognitive Sciences 7(3):134–140. Switch costs in these paradigms run to a few hundred milliseconds and shrink with preparation — real, and far smaller than the recovery times popular writing quotes.)
- An alert you do not answer still costs you the thread, which is the argument for putting the source out of reach rather than resisting it (Stothart, Mitchum & Yehnert (2015), JEP:HPP 41(4):893–897: notifications alone significantly disrupted a demanding attention task even when participants never touched the device.)

04 // The relationships that actually carry a life.
People
Do · Ask one person for one small, specific thing you actually need — a lift, an introduction, twenty minutes on a problem, help carrying something. Ask directly and in person or by voice, and say what it is rather than asking whether they are busy.Do · Send one message to someone you have not spoken to in months, without waiting for a reason. Two lines is enough — say you thought of them and why. Do not open with an apology for the silence.

In a normal week, how many real conversations do you have with someone you care about?

You said People is thin right now.
what the research says
Evidence: moderate· good evidence, some inconsistency
The evidence that people carry a life is about as strong as observational evidence gets: across 148 studies and 308,849 participants, stronger social relationships were associated with a 50% higher likelihood of survival, and the richest measures of connection carried almost all of that signal while living alone carried almost none. The evidence that any particular thing you do next week fixes it is much thinner — so no step in this pack is labelled strong, however large the numbers underneath the domain are. What the research does support is specific: how you answer someone's good news matters more than how you answer their bad news, people reliably underestimate how welcome it is to be contacted, and when loneliness is the problem, the interventions that work best are the ones that change how contact is read rather than the ones that just arrange more of it.

the next ninety days
Send one message to someone you have not spoken to in months, without waiting for a reason. Two lines is enough — say you thought of them and why. Do not open with an apology for the silence.
after the first time each week you pick up your phone out of boredom rather than for something
Evidence: moderate· good evidence, some inconsistency
sources
- People consistently underestimate how much others appreciate being contacted, and the gap is widest with the people they are least close to (Liu, Rim, Min & Min (2023), Journal of Personality and Social Psychology 124(4), 754–771 — a preregistered series of experiments finding robust underestimation of reach-out appreciation. The underestimation was magnified when the contact was more surprising to the recipient and when it came from someone more socially distant, which is precisely the case where a person is least likely to send anything.)
- The same misprediction shows up with strangers: people expect solitude to be the better experience and it reliably is not (Epley & Schroeder (2014), Journal of Experimental Psychology: General 143(5), 1980–1999. Commuters on trains and buses instructed to talk to a stranger reported a more positive and no less productive journey than those who stayed disconnected; separate participants predicted the opposite. The mistaken preference for solitude came partly from underestimating how interested other people were.)
BCTTv1 7.1 Prompts/cues
the next ninety days
Write down the three or four people you would want beside you in a bad week. Next to each name, write the date of the last real conversation you had — not a reaction to something they posted, an actual conversation. Keep the note where you will see it again.
after Sunday evening, when you look at the week ahead
Evidence: moderate· good evidence, some inconsistency
sources
- Keeping track of an outcome you care about is one of the better-evidenced things a person can do about it, and works better when the outcome rather than the activity is what gets recorded (Harkin et al. (2016), Psychological Bulletin 142(2), 198–229 — 138 studies, N = 19,951. Monitoring promoted goal attainment at d+ = 0.40 (95% CI 0.32–0.48), with larger effects when the outcome was monitored and when it was physically recorded. The trials were about goals in general, not about friendship, which is why this is labelled moderate rather than strong.)
- The strength of a person's relationships was associated with survival across a very large body of studies, and the richest measures of connection carried the signal while living alone did not (Holt-Lunstad, Smith & Layton (2010), PLoS Medicine 7(7), e1000316 — 148 studies, 308,849 participants. OR = 1.50 (95% CI 1.42–1.59), a 50% higher likelihood of survival, consistent across age, sex, initial health and cause of death. Strongest for complex measures of social integration (OR = 1.91); weakest and not significant for living alone versus with others (OR = 1.19). Observational.)
- The longest-running study of adult life reports that the quality of people's relationships tracked their later health and happiness, and it is worth knowing exactly who that study was about (Harvard Study of Adult Development, begun 1938 — 724 men in two cohorts: 268 Harvard College sophomores and 456 boys from inner-city Boston, all male, largely white, born around 1920. Observational, so it can show that connection tracks with flourishing and cannot show that adding it causes flourishing for any given person. Cited here as narrative; the causal weight in this pack belongs to the meta-analyses.)
BCTTv1 2.4 Self-monitoring of outcome(s) of behavior
the year
When you decide not to contact someone, write down the sentence you told yourself — “they are busy”, “they would find it odd”, “I always start it” — and then write what you would actually predict happens if you sent it anyway. Send one of them and compare the two.
after the moment you draft a message and then delete it without sending
Evidence: moderate· good evidence, some inconsistency
sources
- Among randomised studies, the loneliness interventions that worked best were the ones addressing how social situations are construed, not the ones that simply arranged more contact (Masi, Chen, Hawkley & Cacioppo (2011), Personality and Social Psychology Review 15(3), 219–266 — 50 studies across four strategies: improving social skills, enhancing social support, increasing opportunities for contact, and addressing maladaptive social cognition. Mean effect sizes were −0.367 for single-group pre-post designs, −0.459 for non-randomised comparisons, and −0.198 (95% CI −0.32 to −0.08) for randomised comparisons. Within the randomised studies the most successful interventions addressed social cognition.)
- The specific prediction people get wrong is how welcome the contact will be, and that error is measurable rather than a matter of encouragement (Liu, Rim, Min & Min (2023), Journal of Personality and Social Psychology 124(4), 754–771 — preregistered experiments documenting robust underestimation of how much recipients appreciate being contacted, magnified with greater social distance. That is the belief this exercise puts to a test rather than argues with.)

what the research says
Evidence: moderate· good evidence, some inconsistency
The best-evidenced things in this domain are unglamorous: when you sleep, whether you move at all, and asking for help early when sleep has been bad for months. Sleep regularity — the day-to-day consistency of when you sleep and wake — predicts mortality better than sleep duration does, and the activity guidelines start from “some is better than none” rather than from an ideal. Food and self-care appear here only as additions — one thing added to a meal you already eat, one appointment finally in the calendar — never as a project to turn a body into something else.

Evidence: strong· replicated, meta-analysed, or guideline-level
sources
- The largest differences in mortality risk appear between doing nothing and doing a small amount of activity. (Garcia et al. 2023, Br J Sports Med 57(15):979–989 — 196 articles, 94 cohorts, >30 million participants. All-cause mortality RR 0.69 (95% CI 0.65–0.73) at 8.75 mMET-hours/week, roughly the recommended 150 min/week; gains above that level were small and uncertain.)
- Modelling put about 111,000 US deaths a year within reach of ten more minutes of activity a day. (Saint-Maurice et al. 2022, JAMA Intern Med 182(3):349–352: 111,174 deaths a year (95% CI 79,594–142,754), a 6.9% reduction, if US adults aged 40–85 added 10 min/day of moderate-to-vigorous activity.)
- Cardiorespiratory fitness was inversely associated with long-term mortality, with no observed upper limit of benefit. (Mandsager et al. 2018, JAMA Netw Open 1(6):e183605 — 122,007 patients, 13,637 deaths. Low vs elite fitness: adjusted HR 5.04 (4.10–6.20); below- vs above-average: HR 1.41. Observational, in a referred clinical population — associated with, not caused by, and not a number to chase on a watch.)

Evidence: strong· replicated, meta-analysed, or guideline-level
sources
- WHO recommends 150–300 minutes of moderate or 75–150 minutes of vigorous activity a week for adults, plus muscle-strengthening work on two days. (WHO 2020 guidelines on physical activity and sedentary behaviour: 150–300 min moderate or 75–150 min vigorous per week, muscle-strengthening for all age groups, and no quantified sedentary threshold because the evidence was insufficient to set one. Headline framing: some physical activity is better than none.)
- Muscle-strengthening activity was associated with lower mortality and disease risk independently of aerobic activity. (Momma et al. 2022, Br J Sports Med 56(13):755–763 — 16 prospective cohorts: 10–17% lower risk of all-cause mortality, cardiovascular disease, total cancer, diabetes and lung cancer. J-shaped, with most of the benefit at roughly 30–60 min a week and no clear gain beyond it.)
- The guideline covers adults, older adults, pregnancy and postpartum, and people living with chronic conditions or disability separately. (Bull et al. 2020, Br J Sports Med 54(24):1451–1462 — the paper behind the WHO guideline, including the population-specific recommendations.)

- Stimulus control is supported as a single-component therapy for chronic insomnia, unlike sleep hygiene advice on its own. (Edinger et al. 2021, J Clin Sleep Med 17(2):255–262: stimulus control as a single-component therapy — CONDITIONAL recommendation. Sleep restriction, the other single component, acutely worsens daytime sleepiness and is not something to run unsupervised.)
- For insomnia lasting months, cognitive behavioural therapy is the recommended first step for all adults, ahead of medication. (Qaseem et al. 2016, Ann Intern Med 165(2):125–133 — American College of Physicians: CBT-I as initial care is a strong recommendation on moderate-quality evidence; adding medication is only a weak recommendation on low-quality evidence.)

the next ninety days
Write for twenty minutes about the thing you keep not saying. No editing, no audience, nobody reads it. Three evenings running, then stop — this is a short course, not a diary.
after you close the laptop for the day, on three evenings you had already planned to be in
Evidence: moderate· good evidence, some inconsistency
sources
- Writing about something that is bothering you has a real average effect across many trials, and it is small (Frattaroli (2006), Psychological Bulletin 132(6):823–865. Random-effects meta-analysis of 146 randomised studies: average effect r = .075. Two earlier and smaller meta-analyses used fixed-effects models, which limited how far their more encouraging results generalised.)
- In people living with a long-term condition, the unfacilitated version showed no benefit for low mood at all, short or long term (Nyssen et al. (2016), Health Technology Assessment 20(27); 64 studies, 59 randomised. Pooled effect on depression: SMD −0.06 (95% CI −0.29 to 0.17, n = 1,563) short term and −0.04 (95% CI −0.18 to 0.10, n = 778) long term, with no effect on anxiety or biomarkers.)
- Revisiting painful feeling in an unstructured way has been reported as harmful, which is why the timer and the three-session limit are part of the step and not decoration (Littrell (1998), Clinical Psychology Review 18(1):71–102. Review distinguishing time-limited, structured disclosure in ordinarily functioning people, which had good supporting evidence, from open-ended emotional expression in clinical samples, where the process can do harm.)
BCTTv1 11.2 Reduce negative emotions
the next ninety days
Send one message to someone you have not spoken to in months, without waiting for a reason. Two lines is enough — say you thought of them and why. Do not open with an apology for the silence.
after the first time each week you pick up your phone out of boredom rather than for something
Evidence: moderate· good evidence, some inconsistency
sources
- People consistently underestimate how much others appreciate being contacted, and the gap is widest with the people they are least close to (Liu, Rim, Min & Min (2023), Journal of Personality and Social Psychology 124(4), 754–771 — a preregistered series of experiments finding robust underestimation of reach-out appreciation. The underestimation was magnified when the contact was more surprising to the recipient and when it came from someone more socially distant, which is precisely the case where a person is least likely to send anything.)
- The same misprediction shows up with strangers: people expect solitude to be the better experience and it reliably is not (Epley & Schroeder (2014), Journal of Experimental Psychology: General 143(5), 1980–1999. Commuters on trains and buses instructed to talk to a stranger reported a more positive and no less productive journey than those who stayed disconnected; separate participants predicted the opposite. The mistaken preference for solitude came partly from underestimating how interested other people were.)

Write down the three or four people you would want beside you in a bad week. Next to each name, write the date of the last real conversation you had — not a reaction to something they posted, an actual conversation. Keep the note where you will see it again.
after Sunday evening, when you look at the week ahead
Evidence: moderate· good evidence, some inconsistency
sources
- Keeping track of an outcome you care about is one of the better-evidenced things a person can do about it, and works better when the outcome rather than the activity is what gets recorded (Harkin et al. (2016), Psychological Bulletin 142(2), 198–229 — 138 studies, N = 19,951. Monitoring promoted goal attainment at d+ = 0.40 (95% CI 0.32–0.48), with larger effects when the outcome was monitored and when it was physically recorded. The trials were about goals in general, not about friendship, which is why this is labelled moderate rather than strong.)
- The strength of a person's relationships was associated with survival across a very large body of studies, and the richest measures of connection carried the signal while living alone did not (Holt-Lunstad, Smith & Layton (2010), PLoS Medicine 7(7), e1000316 — 148 studies, 308,849 participants. OR = 1.50 (95% CI 1.42–1.59), a 50% higher likelihood of survival, consistent across age, sex, initial health and cause of death. Strongest for complex measures of social integration (OR = 1.91); weakest and not significant for living alone versus with others (OR = 1.19). Observational.)
- The longest-running study of adult life reports that the quality of people's relationships tracked their later health and happiness, and it is worth knowing exactly who that study was about (Harvard Study of Adult Development, begun 1938 — 724 men in two cohorts: 268 Harvard College sophomores and 456 boys from inner-city Boston, all male, largely white, born around 1920. Observational, so it can show that connection tracks with flourishing and cannot show that adding it causes flourishing for any given person. Cited here as narrative; the causal weight in this pack belongs to the meta-analyses.)

Put two sessions a week in the calendar as recurring appointments and make your muscles work for twenty minutes in each — bodyweight, bands, or machines.

Evidence: strong· replicated, meta-analysed, or guideline-level
sources
- WHO recommends 150–300 minutes of moderate or 75–150 minutes of vigorous activity a week for adults, plus muscle-strengthening work on two days. (WHO 2020 guidelines on physical activity and sedentary behaviour: 150–300 min moderate or 75–150 min vigorous per week, muscle-strengthening for all age groups, and no quantified sedentary threshold because the evidence was insufficient to set one. Headline framing: some physical activity is better than none.)
- Muscle-strengthening activity was associated with lower mortality and disease risk independently of aerobic activity. (Momma et al. 2022, Br J Sports Med 56(13):755–763 — 16 prospective cohorts: 10–17% lower risk of all-cause mortality, cardiovascular disease, total cancer, diabetes and lung cancer. J-shaped, with most of the benefit at roughly 30–60 min a week and no clear gain beyond it.)
- The guideline covers adults, older adults, pregnancy and postpartum, and people living with chronic conditions or disability separately. (Bull et al. 2020, Br J Sports Med 54(24):1451–1462 — the paper behind the WHO guideline, including the population-specific recommendations.)

Direction, not a schedule. These are the things that need a run-up, and they are here so you know where the earlier steps are pointing.
the year
Put one small thing you used to be glad you had done — a walk to a specific place, half an hour with an instrument, coffee with someone you name — into a specific half-hour, and go whether or not you feel like going.
after the evening you set up the coming week, before anything else claims the slot
Evidence: moderate· good evidence, some inconsistency
sources
- Acting first and letting the mood follow is the best-supported idea in this domain, and it was tested as a structured course rather than as one booked hour (Ekers, Webster, Van Straten, Cuijpers, Richards & Gilbody (2014), PLoS ONE 9(6):e100100. 26 randomised trials, 1,524 participants; behavioural activation vs controls SMD −0.74 (95% CI −0.91 to −0.56). The authors note most included studies were of low quality with short follow-up.)
- In a large randomised trial, scheduling valued activity performed as well as the more complex and more expensive alternative (Richards et al. (2016), Lancet 388(10047):871–880 (COBRA). 440 adults; behavioural activation delivered by junior mental-health workers was non-inferior to cognitive behavioural therapy at 12 months (PHQ-9 mean difference 0.1, 95% CI −1.3 to 1.5).)
- How structured the approach is turns out to matter more than which approach it is, which is the argument for a named activity at a named hour rather than a general intention (Spinhoven et al. (2018), Behaviour Research and Therapy 106:71–85. 36 trials, 3,307 participants; effect on repetitive negative thinking g = 0.48 overall, rising to 0.76 for approaches built specifically around it and 0.57 for standard cognitive behavioural therapy, against 0.14 for a mixed comparison group that included expressive writing, yoga, light therapy and medication.)
BCTTv1 1.4 Action planning
the year
Before the block of work you actually care about, put the phone in another room, close every window that is not the work, and set an end time. One thing until then.
after immediately after you decide what the hardest thing on today's list is
Evidence: reasonable· mechanistically sensible, thinner evidence
sources
- This works by removing the option, not by freeing up mental capacity — the popular claim that a phone on the desk drains your capacity did not generalise when it was tested again (Hartmann, Martarelli, Reber & Rothen (2020), Consciousness and Cognition 86:103033. No overall effect of phone presence on short-term or prospective memory; the only signal was a moderation in participants low in phone dependency.)
- Switching between tasks reliably slows you down and raises errors, and preparing for the switch reduces the cost without removing it (Monsell (2003), Trends in Cognitive Sciences 7(3):134–140. Switch costs in these paradigms run to a few hundred milliseconds and shrink with preparation — real, and far smaller than the recovery times popular writing quotes.)
- An alert you do not answer still costs you the thread, which is the argument for putting the source out of reach rather than resisting it (Stothart, Mitchum & Yehnert (2015), JEP:HPP 41(4):893–897: notifications alone significantly disrupted a demanding attention task even when participants never touched the device.)
BCTTv1 12.1 Restructuring the physical environment

When you decide not to contact someone, write down the sentence you told yourself — “they are busy”, “they would find it odd”, “I always start it” — and then write what you would actually predict happens if you sent it anyway. Send one of them and compare the two.
after the moment you draft a message and then delete it without sending
Evidence: moderate· good evidence, some inconsistency
sources
- Among randomised studies, the loneliness interventions that worked best were the ones addressing how social situations are construed, not the ones that simply arranged more contact (Masi, Chen, Hawkley & Cacioppo (2011), Personality and Social Psychology Review 15(3), 219–266 — 50 studies across four strategies: improving social skills, enhancing social support, increasing opportunities for contact, and addressing maladaptive social cognition. Mean effect sizes were −0.367 for single-group pre-post designs, −0.459 for non-randomised comparisons, and −0.198 (95% CI −0.32 to −0.08) for randomised comparisons. Within the randomised studies the most successful interventions addressed social cognition.)
- The specific prediction people get wrong is how welcome the contact will be, and that error is measurable rather than a matter of encouragement (Liu, Rim, Min & Min (2023), Journal of Personality and Social Psychology 124(4), 754–771 — preregistered experiments documenting robust underestimation of how much recipients appreciate being contacted, magnified with greater social distance. That is the belief this exercise puts to a test rather than argues with.)
BCTTv1 13.2 Framing/reframing

Get out of bed when you have been lying there awake and annoyed, sit somewhere else under a low light with something dull, and go back only when you are sleepy.

Evidence: moderate· good evidence, some inconsistency
sources
- Stimulus control is supported as a single-component therapy for chronic insomnia, unlike sleep hygiene advice on its own. (Edinger et al. 2021, J Clin Sleep Med 17(2):255–262: stimulus control as a single-component therapy — CONDITIONAL recommendation. Sleep restriction, the other single component, acutely worsens daytime sleepiness and is not something to run unsupervised.)
- For insomnia lasting months, cognitive behavioural therapy is the recommended first step for all adults, ahead of medication. (Qaseem et al. 2016, Ann Intern Med 165(2):125–133 — American College of Physicians: CBT-I as initial care is a strong recommendation on moderate-quality evidence; adding medication is only a weak recommendation on low-quality evidence.)

The rest

What we left alone
A tool like this wants to tell you everything that is wrong with you. Here is what we noticed and are deliberately leaving alone.
left alone
- Work & craftworth doing, but not ahead of what you chose.
- Moneyyou told us not now, so we have left it.
- Placeyou said this one is fine, and we believe you.
- Meaningworth doing, but not ahead of what you chose.
That is the whole section. They will be waiting if you want them later, and nothing here will bring them up again.
— // how this stays true
Check-ins
A plan written today is about the life you had today. Check-ins are how it keeps up with the one you actually have.
On a rhythm you choose, we ask the same anchor questions as above — worded identically, so the answers are comparable — and one open one: what changed?
what we'll ask
Mind
In a normal week, how many days do you feel clear-headed rather than scattered?
People
In a normal week, how many real conversations do you have with someone you care about?
Body
On a normal week, how many nights do you get the sleep you actually need?
If a step did not happen, we ask why — whether it was that you did not know how, that there was no room for it, or that you did not want to. Those need different answers, and giving the wrong one is how plans die. Three misses retires a step: that is information about the step, not about you.
Note · You can pause or stop at any point, and nothing will chase you. A plan you drifted away from is still yours when you come back.

- Postponing worry to a fixed later slot cut daily worry time when the postponement was itself framed as a specific if-then plan — McCarrick et al. (2025), Psychology & Health: 4-arm RCT, 186 participants over 14 days. The planned version reported roughly 15 minutes a day less worry than standard postponement. No arm improved any sleep outcome against controls.
- The same technique delivered as a plain online instruction did nothing at all, which is why this is offered as worth trying rather than as reliable — Versluis, Verkuil & Brosschot (2016), British Journal of Health Psychology 21(2):318–335. 996 enrolled, 361 completed; the intervention group did not differ from the registration control on health complaints, worry frequency or worry duration (partial eta-squared = .000).
- Chewing the same thought over predicts low mood arriving, impairs problem solving, and erodes the support around a person — Nolen-Hoeksema, Wisco & Lyubomirsky (2008), Perspectives on Psychological Science 3(5):400–424. Review of response-styles theory: rumination more consistently predicts the onset of a low period than its duration, and dozens of experiments show that turning attention elsewhere relieves it.
- Naming a thought as a thought, rather than arguing with its content, has held up in controlled laboratory component studies — Levin, Hildebrandt, Lillis & Hayes (2012), Behavior Therapy 43(4):741–756. Meta-analysis of 66 laboratory component studies; defusion showed significant positive effects against inactive comparisons, and conditions using an actual exercise beat conditions offering only the rationale.
- Acting first and letting the mood follow is the best-supported idea in this domain, and it was tested as a structured course rather than as one booked hour — Ekers, Webster, Van Straten, Cuijpers, Richards & Gilbody (2014), PLoS ONE 9(6):e100100. 26 randomised trials, 1,524 participants; behavioural activation vs controls SMD −0.74 (95% CI −0.91 to −0.56). The authors note most included studies were of low quality with short follow-up.

(2018), Behaviour Research and Therapy 106:71–85. 36 trials, 3,307 participants; effect on repetitive negative thinking g = 0.48 overall, rising to 0.76 for approaches built specifically around it and 0.57 for standard cognitive behavioural therapy, against 0.14 for a mixed comparison group that included expressive writing, yoga, light therapy and medication.
- Writing about something that is bothering you has a real average effect across many trials, and it is small — Frattaroli (2006), Psychological Bulletin 132(6):823–865. Random-effects meta-analysis of 146 randomised studies: average effect r = .075. Two earlier and smaller meta-analyses used fixed-effects models, which limited how far their more encouraging results generalised.
- In people living with a long-term condition, the unfacilitated version showed no benefit for low mood at all, short or long term — Nyssen et al.

Pooled effect on depression: SMD −0.06 (95% CI −0.29 to 0.17, n = 1,563) short term and −0.04 (95% CI −0.18 to 0.10, n = 778) long term, with no effect on anxiety or biomarkers.

Review distinguishing time-limited, structured disclosure in ordinarily functioning people, which had good supporting evidence, from open-ended emotional expression in clinical samples, where the process can do harm.
- Against active controls, mindfulness programmes showed moderate evidence for anxiety, low mood and pain, and low or insufficient evidence for everything else claimed for them — Goyal et al. (2014), JAMA Internal Medicine 174(3):357–368. 47 trials, 3,515 participants, active controls only. Anxiety ES 0.38 (95% CI 0.12–0.64) at 8 weeks and 0.22 at 3–6 months; depression 0.30 then 0.23; pain 0.33. Low or insufficient evidence for positive mood, attention, substance use and sleep, and no evidence that meditation beat any active comparison.
- Unwanted effects are real and under-reported, and they occur in people with no previous history of mental-health difficulty — Farias, Maraldi, Wallenkampf & Lucchetti (2020), Acta Psychiatrica Scandinavica 142(5):374–393. 83 studies, 6,703 practitioners; pooled adverse-event prevalence 8.3% (3.7% in experimental studies, 33.2% in observational ones), most commonly anxiety, low mood and cognitive anomalies.
- The published trial literature reports far more successes than a field with this effect size should produce, so read the headline findings down — Coronado-Montoya et al. (2016), PLoS ONE 11(4):e0153220. 108 of 124 published trials (87%) reported a positive outcome in the abstract against about 66 expected; 13 of 21 registered trials were still unpublished 30 months after completion.
- Fifteen researchers in the field, several of them practitioners, published a joint account of how weak the methods behind the popular claims are — Van Dam et al. (2018), Perspectives on Psychological Science 13(1):36–61, “Mind the Hype”: no agreed definition of the construct, poor blinding, weak active controls, and adverse effects rarely measured.
- Simply receiving an alert, without picking the phone up, disrupted an attention task about as much as actually using the phone did — Stothart, Mitchum & Yehnert (2015), Journal of Experimental Psychology: Human Perception and Performance 41(4):893–897. Notification-only condition produced distraction comparable in magnitude to active calls or texting.
- The widely repeated claim that heavy media multitasking makes people generally more distractible did not survive correction for small-study effects — Wiradhany & Nieuwenstein (2017), Attention, Perception & Psychophysics 79(8):2620–2641. Two replications plus a meta-analysis of 39 effect sizes: a weak association that turned non-significant once small-study effects were corrected for.
- Screen time in general is a much smaller factor in how people feel than the public conversation assumes, so treat this as removing an interruption rather than as a detox — Orben & Przybylski (2019), Nature Human Behaviour 3:173–182. Specification curve analysis across three datasets, n = 355,358: digital technology use explained at most 0.4% of the variation in wellbeing.
- This works by removing the option, not by freeing up mental capacity — the popular claim that a phone on the desk drains your capacity did not generalise when it was tested again — Hartmann, Martarelli, Reber & Rothen (2020), Consciousness and Cognition 86:103033. No overall effect of phone presence on short-term or prospective memory; the only signal was a moderation in participants low in phone dependency.
- Switching between tasks reliably slows you down and raises errors, and preparing for the switch reduces the cost without removing it — Monsell (2003), Trends in Cognitive Sciences 7(3):134–140. Switch costs in these paradigms run to a few hundred milliseconds and shrink with preparation — real, and far smaller than the recovery times popular writing quotes.
- Mentally leaving work alone in off-hours is associated with less exhaustion, better sleep and higher life satisfaction, at small to medium size — Wendsche & Lohmann-Haislah (2017), Frontiers in Psychology 7:2072. 86 publications, 91 independent samples, 38,124 employees. Small-to-medium associations on self-reported health and state wellbeing; no significant association with physiological stress indicators, and small negative associations with creativity and contextual performance.
- It is the continued mental chewing, not the event, that keeps the stress response running — which is the difference between a demanding day and a day with no recovery in it — Brosschot, Gerin & Thayer (2006), Journal of Psychosomatic Research 60(2):113–124. Review of the perseverative cognition hypothesis: worry and rumination prolong cardiovascular, endocrine, immune and neurovisceral activation both before and after the stressor itself.
- Support from a person makes self-guided approaches work better, and the gap is widest for the people who are struggling most — Karyotaki et al. (2021), JAMA Psychiatry 78(4):361–371. Individual-patient-data network meta-analysis, 39 randomised trials, 9,751 participants: guided internet CBT beat unguided at post-treatment (PHQ-9 mean difference −0.8, 95% CI −1.4 to −0.2), with little difference for people in the mild or subthreshold range.
- US federal guidance names a primary care provider as a normal first route — they can do an initial check and refer you onward — National Institute of Mental Health, “Help for Mental Illnesses”: lists primary care, the SAMHSA locator, insurer directories and employer assistance programmes as routes in, and puts the 988 Suicide & Crisis Lifeline ahead of all of them.
- Keeping track of an outcome you care about is one of the better-evidenced things a person can do about it, and works better when the outcome rather than the activity is what gets recorded — Harkin et al.

OR = 1.50 (95% CI 1.42–1.59), a 50% higher likelihood of survival, consistent across age, sex, initial health and cause of death. Strongest for complex measures of social integration (OR = 1.91); weakest and not significant for living alone versus with others (OR = 1.19). Observational.

- People consistently underestimate how much others appreciate being contacted, and the gap is widest with the people they are least close to — Liu, Rim, Min & Min (2023), Journal of Personality and Social Psychology 124(4), 754–771 — a preregistered series of experiments finding robust underestimation of reach-out appreciation. The underestimation was magnified when the contact was more surprising to the recipient and when it came from someone more socially distant, which is precisely the case where a person is least likely to send anything.
- The same misprediction shows up with strangers: people expect solitude to be the better experience and it reliably is not — Epley & Schroeder (2014), Journal of Experimental Psychology: General 143(5), 1980–1999. Commuters on trains and buses instructed to talk to a stranger reported a more positive and no less productive journey than those who stayed disconnected; separate participants predicted the opposite. The mistaken preference for solitude came partly from underestimating how interested other people were.
- Sharing something good with another person was associated with more positive affect and higher wellbeing than the good thing itself accounted for, and enthusiastic engaged responses enhanced the benefit further — Gable, Reis, Impett & Asher (2004), Journal of Personality and Social Psychology 87(2), 228–245 — four studies. Two daily-experience studies found telling someone about a positive event predicted increased daily positive affect and wellbeing above the impact of the event itself; benefits were greater when the other person responded actively and constructively rather than passively or dismissively. Two further studies found close relationships whose partner typically responded enthusiastically had higher relationship wellbeing. The sampling was close relationships, principally couples; there is no comparable four-study base for friends, siblings or colleagues, which is why the label here is moderate rather than strong.
- Loneliness and social isolation sat alongside established mortality risk factors in the pooled data, and the effect was larger in samples averaging under 65 — Holt-Lunstad, Smith, Baker, Harris & Stephenson (2015), Perspectives on Psychological Science 10(2), 227–237. After controls: social isolation OR = 1.29, loneliness OR = 1.26, living alone OR = 1.32. No difference between objective and subjective isolation. Social deficits were more predictive of death in samples averaging under 65 — this is not only an old-age question.
- Plans that fix both a time and a place outperform plans that fix only one, which is the whole of the case for putting this in a calendar rather than intending it — Sheeran, Listrom & Gollwitzer (2024), European Review of Social Psychology 36(1), 162–194 — 642 tests. Naive average d = .36; after robust Bayesian correction for publication bias d = .15 (CI .08–.22). Both time and place specified: d = .46, versus .25 for one alone. Note also that no trial has tested “schedule a friend” as such; the scheduling evidence is general, and this practice is labelled reasonable for that reason.
- Among randomised studies, the loneliness interventions that worked best were the ones addressing how social situations are construed, not the ones that simply arranged more contact — Masi, Chen, Hawkley & Cacioppo (2011), Personality and Social Psychology Review 15(3), 219–266 — 50 studies across four strategies: improving social skills, enhancing social support, increasing opportunities for contact, and addressing maladaptive social cognition. Mean effect sizes were −0.367 for single-group pre-post designs, −0.459 for non-randomised comparisons, and −0.198 (95% CI −0.32 to −0.08) for randomised comparisons. Within the randomised studies the most successful interventions addressed social cognition.
- People substantially underestimate how likely others are to say yes to a direct request for help — Flynn & Lake (2008), Journal of Personality and Social Psychology 95(1), 128–143 — a series of studies in which help-seekers underestimated by as much as 50% the likelihood that others would agree to a direct request. In Study 1, participants expected to have to approach roughly twice as many people as they actually needed to. The mechanism: askers weigh the cost of helping, and overlook the social cost to the other person of refusing.
- Performing acts of kindness produced a small-to-medium improvement in the wellbeing of the person doing them, with no sign of publication bias — Curry, Rowland, Van Lissa, Zlotowitz, McAlaney & Whitehouse (2018), Journal of Experimental Social Psychology 76, 320–329 — 27 studies, total N = 4,045, 52 effect sizes. Overall δ = 0.28, not moderated by sex, age, participant type, intervention, control condition or outcome measure, with no indication of publication bias. Small and real: read it as worth doing, not as transformative.
- Day-to-day consistency of sleep timing predicted all-cause mortality better than sleep duration did. — Windred et al. 2024, Sleep 47(1): Sleep Regularity Index from >10 million hours of accelerometry in 60,977 UK Biobank adults; 1,859 deaths over a mean 6.3 years. The top four regularity quintiles had 20–48% lower all-cause mortality than the least regular quintile. Observational: it shows regularity predicts risk, not that changing yours changes your risk.
- More time in daytime outdoor light was associated with easier waking and fewer reported insomnia symptoms. — Burns et al. 2021, J Affect Disord 295:347–352, UK Biobank (n ≈ 502,000; median 2.5 daylight hours outdoors per day). Each additional hour outdoors: greater ease of getting up (OR 1.46–1.49), fewer insomnia symptoms (OR 0.94–0.97), earlier chronotype (OR 0.75–0.77). Cross-sectional and longitudinal associations; the longitudinal effects were smaller.
- Evening light-emitting screen use delayed the circadian clock, suppressed melatonin and reduced next-morning alertness. — Chang et al. 2015, PNAS 112(4):1232–1237 — a small inpatient crossover trial. Real mechanism, small sample; enough to justify dimming the evening, not enough to promise a night's sleep.
- Sleep hygiene advice used on its own is the weakest of the behavioural sleep components, and the guideline suggests against it as a single therapy. — Edinger et al. 2021, AASM clinical practice guideline, J Clin Sleep Med 17(2):255–262: multicomponent CBT-I is a STRONG recommendation; sleep hygiene as a single-component therapy is recommended against (conditional).
- For insomnia lasting months, cognitive behavioural therapy is the recommended first step for all adults, ahead of medication. — Qaseem et al. 2016, Ann Intern Med 165(2):125–133 — American College of Physicians: CBT-I as initial care is a strong recommendation on moderate-quality evidence; adding medication is only a weak recommendation on low-quality evidence.
- The largest differences in mortality risk appear between doing nothing and doing a small amount of activity. — Garcia et al. 2023, Br J Sports Med 57(15):979–989 — 196 articles, 94 cohorts, >30 million participants. All-cause mortality RR 0.69 (95% CI 0.65–0.73) at 8.75 mMET-hours/week, roughly the recommended 150 min/week; gains above that level were small and uncertain.
- Modelling put about 111,000 US deaths a year within reach of ten more minutes of activity a day. — Saint-Maurice et al. 2022, JAMA Intern Med 182(3):349–352: 111,174 deaths a year (95% CI 79,594–142,754), a 6.9% reduction, if US adults aged 40–85 added 10 min/day of moderate-to-vigorous activity.
- Cardiorespiratory fitness was inversely associated with long-term mortality, with no observed upper limit of benefit. — Mandsager et al. 2018, JAMA Netw Open 1(6):e183605 — 122,007 patients, 13,637 deaths. Low vs elite fitness: adjusted HR 5.04 (4.10–6.20); below- vs above-average: HR 1.41. Observational, in a referred clinical population — associated with, not caused by, and not a number to chase on a watch.
- WHO recommends 150–300 minutes of moderate or 75–150 minutes of vigorous activity a week for adults, plus muscle-strengthening work on two days. — WHO 2020 guidelines on physical activity and sedentary behaviour: 150–300 min moderate or 75–150 min vigorous per week, muscle-strengthening for all age groups, and no quantified sedentary threshold because the evidence was insufficient to set one. Headline framing: some physical activity is better than none.
- Muscle-strengthening activity was associated with lower mortality and disease risk independently of aerobic activity. — Momma et al. 2022, Br J Sports Med 56(13):755–763 — 16 prospective cohorts: 10–17% lower risk of all-cause mortality, cardiovascular disease, total cancer, diabetes and lung cancer. J-shaped, with most of the benefit at roughly 30–60 min a week and no clear gain beyond it.
- The guideline covers adults, older adults, pregnancy and postpartum, and people living with chronic conditions or disability separately. — Bull et al. 2020, Br J Sports Med 54(24):1451–1462 — the paper behind the WHO guideline, including the population-specific recommendations.
- Higher fruit and vegetable intake was associated with lower all-cause mortality across a large body of prospective studies. — Aune et al. 2017, Int J Epidemiol 46(3):1029–1056 — 95 studies. All-cause mortality RR 0.90 (95% CI 0.87–0.93) per additional 200 g/day of fruit and vegetables. Observational, and about what is added rather than what is removed.
- Higher dietary fibre intake was associated with lower all-cause and cardiovascular mortality, with the certainty of evidence graded moderate. — Reynolds et al. 2019, Lancet 393(10170):434–445 — 185 prospective studies and 58 trials, just under 135 million person-years: 15–30% lower all-cause and cardiovascular mortality in the highest fibre consumers versus the lowest.
- Writing down both a day and a time raised uptake of a free on-site vaccination clinic; writing down a day alone did not. — Milkman et al. 2011, PNAS 108(26):10415–10420, randomised field experiment: uptake rose 4.2 percentage points from a 33.1% base when the prompt asked for a date and a time; the date-only prompt gained a non-significant 1.5 points. Small, real, and the kind of size to expect.
- Putting off dental visits tracks with worse self-rated oral health and visits driven by pain, which sustains the avoidance. — Armfield, Stewart & Spencer 2007, BMC Oral Health 7:1 — 6,112 Australian adults: 29.2% of those very afraid of the dentist had delayed visiting, poor oral health and pain-driven attendance, against 11.6% of those with no such fear.
