Each night, write down three things that went well that day and one line on why. It sounds small. It is small — but the mind is built to remember threats far better than it remembers ease, and this practice puts a thumb on that scale.
What is happening
Attention is not neutral. It is tuned, by long habit, to scan for what went wrong — the one sharp comment in a day of kindness, the one delay in a day that mostly worked. Writing down what went well, and naming a reason, pulls attention somewhere it doesn’t go on its own.

Write three good things, every night.
Because a day reviewed for what worked is remembered differently than a day left to the worst moment in it.
A slower exhale as you write the third one down — the day settling instead of just ending.
2 of 5
Name why it happened.
Because a reason moves the good thing from luck to something you had a hand in, or someone you can credit.
A small warmth in the chest when the reason points back to you, or to someone you’re glad to think of.

Small counts the same as big.
Because the habit being trained is noticing, and small things give it the most practice.
Holding a warm cup a second longer, noticing the light on a wall you walk past daily.

The noticing is what trains.
Because what gets rehearsed at night is what the mind reaches for first the next day.
Catching a good moment as it happens, before you've even sat down to write — that's the practice working.

It builds slowly, not tonight.
Because in the best-known study, by Seligman and colleagues, the benefit showed up weeks later and lasted months.
Shoulders a little less braced by the second week, though nothing outside has changed yet.
The practice
Tonight, before sleep, write three things that went well today — big or small — and one line on why each happened. Keep it to a sentence or two per thing. Do it for two weeks before deciding whether it's working.
Not everything today was fine. But some of it was good, and tonight you let yourself notice.
This is a teaching, not treatment. If you’re struggling, a doctor or therapist can help. If you’re in danger right now, call your local emergency number or a crisis line (in the US, call or text 988).
