Right, the science bit

The research your affirmations are built on

The rules we follow when we write your affirmations come from published research, and every study is named and dated below so you can go and read it yourself.

Where the rules come from

These are the ones that decided how a track is written.

36,419students

The largest review of self-affirmation research so far, pulling together 144 separate studies of students who spent a few minutes writing about what mattered most to them. They spoke up more in class, stuck at the work in front of them, and thought better of themselves. The biggest gains were in how they felt.

1 · Healthcare, 2024
17,748people

Published in American Psychologist last year. Self-esteem up. Stress, anxiety and body dissatisfaction down. In one of the studies, students who spent those few minutes writing kept more of their friendships and made more new ones over a term.

2 · American Psychologist, 2025
144tests

This review asked whether writing about what matters to you changes what people do, not only how they say they feel. Across 46 tests of real behaviour it changed what they ate, what they drank, and whether they smoked. Of the three things it measured, what people actually did changed the most, more than their attitudes or their intentions.

3 · Health Psychology, 2015
80students

A single study, so you can see the shape of one. Students wrote down what mattered most to them, then sat a hard problem-solving test. The ones under the most stress did better than the stressed students who had written nothing, and ended up scoring about the same as everybody else.

Why the planner runs to 66 days

There is no one number that fits everybody, so the planner is built around the range the research actually found.

In the study everyone quotes, the fastest people had a new habit locked in within 18 days. 66 is the middle of the range, not a target to hit, and where you land depends on you and on the habit you have picked. That range is why the planner runs to 66 days. Most people will have it by then, and some will have it a lot sooner.

The planner is for the habit you are building, not for the audio. There is no rule about listening every day. Missing a day does not undo your progress or tell you off for it. You put a track on when you want it.

5 · Lally et al., 2010

What is actually in the 66 days

The planner is not 66 reminders. It runs in 10 weeks, and each week is doing a different job. Everything in it is written around the goal you described, in the words you used.

The first 4 weeks build the behaviour. Week 1 you change nothing at all, you only watch what you already do. Week 2 attaches the new thing to something you already do every day, like the kettle boiling or sitting down at your desk. Week 3 turns it into a plan in the form ‘when this happens, I will do that’, including 2 or 3 plans for what you will do when it goes wrong. Week 4 shrinks it until it is too small to skip.

The next 3 weeks work on belief. Looking for proof you are already partly the person who does this. Saying it in the present tense, as who you are now rather than who you are trying to become. And deciding in advance what happens on the days it does not happen. Day 46 says, in as many words: miss today on purpose, come back tomorrow, nothing bad happens.

The last 3 weeks are about it becoming ordinary. Doing it before you feel ready, looking back at week 1, writing down what you are glad of, and choosing the one thing you want to keep.

Every day is one instruction you can do in under 5 minutes, on a normal bad day, with no equipment and nobody else's help. Each one has 2 lines to write on and a box to tick. On day 18 there is a checkpoint, because 18 days was the fastest anyone in the study formed a habit, and it helps to be told that not having it yet is completely normal.

The methods underneath are habit stacking, planning your next step in advance, planning for the days it goes wrong, keeping your own record, taking the friction out, language about who you are rather than what you are attempting, gratitude for particular things rather than general ones, and telling one person.

The 12 areas, and what each one is built on

Every area is written around what actually helps with that one thing, so the words you get for sleep are not the words you get for grief. Here is what sits behind each of them.

Career & work

Built around the actual goal in front of you at work, not generic career advice. Every affirmation comes with a next step, because change happens through what you do, not just what you believe.

Sleep

Naming what is still undone before bed, rather than carrying it. In one lab study, people who wrote a short to-do list at bedtime fell asleep faster than those who wrote about the day just gone.6 · J Exp Psychol, 2018

Focus & productivity

Naming what pulled you away, rather than trying to force concentration. You have to notice what pulled you away before you can do anything about it.

Confidence & self-esteem

Built on self-efficacy: believing you can do something predicts whether you do. Every affirmation comes with a next step, because belief and action feed each other.

Stress & anxiety relief

A breathing pattern of two breaths in and one long breath out, plus a shift in how you read the feeling. People taught to see stress as their body gearing up, rather than as damage, coped better with a hard task and their bodies settled more quickly afterwards.7 · Crum et al., 2017

Motivation

Built on deciding your next step in advance and putting it in the form ‘when this happens, I will do that’. A meta-analysis of 94 studies found this reliably improves whether people follow through, not just whether they mean to.13 · Gollwitzer & Sheeran, 2006

Money & abundance

When money is tight, attention narrows onto the shortfall, and there is less of it left for anything else, including decisions about money. The words for this area work on widening that back out, so you can think about money instead of only dreading it.

Relationships & connection

Putting a precise name to what you feel. Labelling an emotion reliably lowers how strongly your body reacts to it, even though most people expect the opposite.8 · Psych Science, 2007

Grief, heartbreak & letting go

Built on how grief actually moves: back and forth between facing the loss and getting on with ordinary life, with both treated as normal. It is not built on the 5 stages, which came from interviews with dying patients rather than bereaved people, and which reviews have found does not describe real grief.9 · Stroebe et al., 2017

Gratitude & self-love

Gratitude practice has been tested across 28 countries and 163 separate samples, and the result was a clear lift in wellbeing.10 · PNAS, 2025

Health & vitality

Small daily habits that survive a bad week, rather than starting again every Monday. If you miss a day, the days before it still count, so there is nothing to go back to the beginning of.

Calmer parenting

This one works on what you say to yourself in the moment things boil over, because that is the part you can actually change, and a calmer adult settles a room faster than anything else. No guilt, and no list of things you should have done.

The 5 minute resets

A 5 minute reset is for right now: at your desk, at 3am, 10 minutes before a conversation you are dreading. A track is something you ask for and then listen to whenever you like. A reset is written and delivered on the spot, for the exact thing happening today.

A 5 minute reset does not fix the thing that is worrying you. It gives you a few minutes to breathe and work out what you can actually do something about today.

Personal members have their own set, written for a life rather than a job. They cover being awake in the night, things being hard with someone close, not feeling like enough, money, loneliness, grief, waiting for news, and looking after someone else.

The breathing changes with the situation

The ‘Overwhelmed’ and ‘Stressed’ resets use two breaths in and one long breath out. In a trial of 108 people doing 5 minutes a day for a month, it lifted mood and slowed breathing more than mindfulness meditation did.11 · Cell Reports Med, 2023

The ‘Can't switch off’ and ‘Struggling with sleep’ resets use a slower pattern, with the breath out longer than the breath in, because settling down for the night asks for something different from steadying yourself in a spike.

Then something matched to the situation

Naming a feeling precisely instead of vaguely. Finding the evidence against a doubt. Separating what you can act on from what is just circling. Writing down what is undone before bed.

Each one is short enough to do anywhere with headphones in, which was the whole point of building them.

The sound underneath your tracks

Ocean and rain

These are the ones with the research behind them. People put through a stressful task recovered up to 37% faster listening to natural sound than to noise.12 · IJERPH, 2010

Pink noise and binaural beats

Newer, and with far less evidence behind them than ocean and rain, though plenty of people swear by them for sleep and focus. They are here because members asked for them, and you can pick whichever one works for you.

The 4 hour overnight track is built to cover several full sleep cycles rather than stopping partway through one. And the moon marking the rhythm of your week is simply a ritual we love.

The numbers, for employers

£30,614Average cost of replacing one employeeOxford Economics, 2014
9.4 daysSickness absence per employee a year, the highest in over 15 yearsCIPD, 2025
£51bnAnnual cost of poor mental health to UK employersDeloitte, 2024
£4.70Returned for every £1 spent supporting mental healthDeloitte, 2024

Deloitte also found the money comes back faster from support people use before things get bad than from support that waits for a crisis. That is the argument for something an employee can open on a normal Tuesday, in their own words, without having to ask anyone.

Books, not studies

Not all of this came out of journals. Some of it came from books, and from years of using this on myself. We would rather tell you which is which.

The part of all that the research backs: holding a goal in mind changes what you notice, and what you notice changes what you do about it.
