People arrive at this site with more or less the same sentence: they were told to come back in a year, and nobody told them what to do on Monday morning.
It isn't that the advice was wrong. It's that "eat better and move more" is not an instruction — it's a category. You can't do a category on a Tuesday after a nine-hour shift. So this page is the smaller, duller thing that actually works: one ordinary change at a time, chosen so it survives your worst week rather than your best one.
You've probably done a January. New app, new tracking, new shopping list, all starting Monday. By February it had gone — and the story you were left holding wasn't "that plan was badly designed", it was "I don't stick at things".
That's the real damage. The plan cost you a fortnight; the story costs you the next attempt.
Everything-at-once fails for a boring reason: it needs a good week to run on. Change six things and you need six things to go right. Change one, and it can survive a late finish, a bad night's sleep and somebody else's birthday cake.
Not the most impressive one. The most survivable one. The test takes ten seconds: picture the worst realistic day of your month — the nine-hour shift, the school run, the delayed train, the tea that happens at nine o'clock — and ask whether the thing would still have happened. If the honest answer is no, it's too big. Halve it.
Things that tend to pass that test:
None of them look like much. That is the entire point — the ones that look like much are the ones that disappear.
New habits don't run on motivation, they run on a cue: something that already happens at the same point every day whether you feel like it or not. "After the kettle goes on." "When the six o'clock news starts." "As soon as my plate's in the sink." Those are reliable. "At some point today" is not a cue, it's a hope.
Write it as one sentence with the cue in it: after I've put my plate in the sink, I put my shoes on and walk to the end of the road and back. That sentence is the whole plan. If you can't get it into one line, it's still too big.
Almost everybody starts at the target instead of at the beginning. Ten minutes feels too small to bother with, so they start at thirty — and thirty is the one they skip on Thursday.
The first job of a new habit isn't the benefit, it's proving to yourself that it happens. A habit that exists can be grown later. An ambitious one that keeps getting skipped just teaches you that you skip.
Here I have to be straight with you. I am not going to tell you what any habit will do to anything a doctor measures. I don't know, and it isn't mine to say. That's your GP's ground and it stays there.
What you can honestly judge in a fortnight is this: did the thing happen on the bad days? It's a better question than it sounds. A habit that happened eleven days out of fourteen, including the Tuesday after the nine-hour shift, is a habit you own. One that happened on the seven good days is still a mood.
Every habit breaks. Travel, illness, a rough fortnight, Christmas. The people who keep habits aren't the ones who never miss — they're the ones who restart on the next ordinary day without turning a missed week into a story about themselves.
Saturday is going to happen. So is takeaway night. Takeaway night is not a moral event, and neither one of them ends anything.
| When | What you're doing |
|---|---|
| Days 1–3 | One thing, the small version, attached to a cue that already happens. Nothing else changes. |
| Days 4–7 | Same thing, same cue, same size. If you missed one, restart the next day — and don't add anything to make up for it. |
| Days 8–11 | Still the same one thing. This is the boring stretch, and the boring stretch is the whole exercise. |
| Days 12–14 | Look back. Did it happen on the bad days? If yes, grow it slightly or add a second thing. If no, make it smaller — not bigger. |
A shape, not a prescription. Slower is completely fine. Nobody is timing you.
How long before I notice a difference?
Be careful of anyone who gives you a number for that. What you can see inside a fortnight is whether the habit is real — whether it happened on the days it was hard. Your health, your test results and your medication stay with your GP.
One thing feels far too slow. Can I do three?
You can, and most people do, and it's the commonest reason people are back at the start in March. Slow isn't the price of this method — it's the feature. One thing is what's still standing at Easter.
Should I be doing this instead of what my doctor told me?
No. Never instead. Whatever your GP has asked of you comes first and this sits around it. If the two ever seem to conflict, your GP wins and I'd want you to say so to them.
