The daily note habit - what to write each day and why it compounds

A daily note is the simplest record-keeping habit there is: one page per day, dated, for whatever happened. Notes apps like Obsidian and Logseq made it popular by creating today’s page automatically, but the idea is old. Lab notebooks, ship’s logs and engineers’ day books all work the same way.

Its power comes from compounding. One day’s note is trivial. A year of them answers questions you did not know you would ask.

What to put in it

Keep a loose structure, roughly:

• Plan: the one to three things that matter today.
• Log: what actually happened, a line at a time, as it happens.
• Notes: anything learned, decided or worth remembering.
• Tomorrow: anything to carry over.

You will not fill every section every day. That is fine.

Keep it to five minutes

The habit dies when it feels like journaling. Rules that keep it short:

• Lines, not paragraphs.
• Write as it happens, not at the end of the day from memory.
• No formatting effort. Plain text is fine.
• Skip days without guilt. A note for 4 out of 5 days is plenty.

Where daily notes earn their keep

• “When did we decide that?” Search the notes.
• Standups and status updates. Yesterday’s log is the update.
• Performance reviews. A year of daily lines is a self-review waiting to be edited. See how to keep a work log on Windows.
• Spotting patterns. “Every Monday is wrecked by the same meeting” becomes visible.

Daily note vs task list

They are different tools. The task list is about the future: what you have to do. The daily note is about the past and present: what happened. Mixing them produces a task list full of stale log entries, or a daily note full of undone todos. Keep tasks in the task system and link to them if needed.

Capturing into a daily note quickly

The friction is getting each line in without switching to the notes app. Options:

• Keep the note open on a second monitor.
• Use a capture shortcut that appends to the note.
• Capture into a quick-capture tool and consolidate later.

Jot can play the last role. Every capture is timestamped, the Today screen shows everything captured today, and its “Daily plan” template gives a dated starting line for the morning plan. Notes captured during the day are searchable by date and text later. See search that covers yesterday.

Keep it in plain text if you can

Daily notes are a long-term record. A format that will still open in 20 years matters. Markdown files in a folder are ideal; Jot’s export writes every note as its own Markdown file, named by date. See export your notes as Markdown.

The “interstitial journaling” idea, popularised by Tony Stubblebine on Medium’s engineering and productivity writing, is a close cousin: write a line every time you switch tasks. It works for the same reason: tiny entries, written in the moment.

Jot is on the Microsoft Store.

Jot is a quick-capture app for Windows: one hotkey, one line, back to what you were doing. What it is, or what is still unproven.
