# How to start a one-line-a-day diary today

Updated: 2026-09-01

You need somewhere to write one sentence. That's it.

## The minimum viable first entry

Write, or say, one sentence about today. Not three. One. "Cold morning, the bus was late, made it to work fine." Stop there. That's a finished entry, not a rough draft of a longer one.

## You need

- A notebook, a notes app, or a voice recorder

- Ten seconds, not two minutes: this is the shortest format on this site

- Nothing else. No prompt, no theme, no minimum detail.

## Day 1

Pick the moment right before bed, or right after your alarm. Write one sentence about today. If it starts running to two sentences, cut it to one before you stop.

## Week 1

Same moment, same rule: one line. Don't reread what you wrote yesterday before writing today's. The five-year-diary version of this format is built to be read back in bulk, later, not day by day.

## When you miss a day

Skip it and move on. Writing two lines the next day to cover the gap breaks the format, since the whole point of one-line-a-day is that it's small enough to never feel like it's behind. There is no makeup entry in this method.

## A note on the evidence

There's no dedicated research on this format, positive or negative. Full accounting on the method page (/methods/one-line-a-day). The case for trying it is that it's small enough to actually finish, not that a study proved it works.

Try it by voice: Brain Dump (https://apps.apple.com/us/app/braindump-voice-note-journal/id6473446030): say one sentence before bed and it builds the same year-over-year archive a five-year diary is designed for.

For the full picture, including who else uses this format, see the one-line-a-day method page (/methods/one-line-a-day).
