One line a day journal: the smallest journaling habit that lasts

One line a day is the journaling habit for people who've started journals and stopped. It takes twenty seconds, so it survives tired evenings.

The method

Why short entries last

A long entry asks for time and energy at the end of the day, which is exactly when you have the least. A single line removes that cost. On the evenings you want to write more, you still can.

Reading it back

The value shows up on the weekly read: seven lines side by side show what kept coming up. In Quiet Journal, Sunday brings a short letter that does this for you, put together on your iPhone from your own lines.

One line a day, in colour

Quiet Journal asks for one colour and one line each evening. Every Sunday your iPhone writes you a short letter about your week, and nothing ever leaves your phone.

Questions

What do you write in a one line a day journal?

The single thing about today you'd want to remember: what happened, how it felt, or something someone said. If nothing comes, describe the weather or the colour of the day.

Is one line a day enough?

For building a habit, yes. One line a day is 365 lines a year, and reading them back shows patterns you'd never notice day to day.

Paper or app for a one line a day journal?

Five-year paper diaries are classic. An app is always with you, can lock with Face ID, and can show your lines back as weeks and months.
