Most journaling habits die the same way: you promise yourself a thoughtful evening entry, skip one busy day, feel behind, and quietly stop. Interstitial journaling — a term coined by Tony Stubblebine — fixes this by shrinking the unit of work. Instead of one big reflective entry, you write a single line in the gaps between tasks: what you just finished, what you're about to start, and whatever is on your mind.
It looks like this:
09:12 finished the standup, felt long again 09:14 starting the billing bug — hypothesis: timezone 11:02 fixed. it was the timezone. logging this for future me 11:05 coffee, then reviewing Ali's PR
The magic is in the switch points. Writing one sentence when you change tasks forces a tiny moment of reflection (did that meeting need to happen?) and a tiny moment of intention (what exactly am I starting?). Research on task-switching suggests that residual attention from the previous task degrades the next one — a one-line note is a cheap way to close the loop and start clean.
Why a day-based notes app fits this perfectly
Interstitial journaling has one structural requirement: today's notes should all land in one place, with zero filing decisions. Any friction — choosing a folder, naming a file, finding yesterday's doc — kills the habit, because each entry is only worth a few seconds of effort.
This is why people practice it in day-based tools. In Hejour, the app opens on Today — there is nowhere else to put a note, which is exactly the point. A few habits that help:
- Capture without switching apps. A global shortcut (⇧⌘M in Hejour) pops a small field, you type the line, hit return, and you never left your editor or browser. App-switching is where micro-journaling habits go to die.
- Let todos and journal lines mix. A day is not just prose —
[] call the bankbelongs next to 10:40 bank called back, resolved. Unfinished todos should follow you to tomorrow automatically instead of guilt-tripping you from an old page. - Write for future-you, not for posterity. The searchable log is the real payoff. Six weeks later, “when did we ship the migration?” is one ⌘P search away.
- Plan forward from the middle of a day. Half of journaling is noticing things that belong to another day. Typing
@in Hejour opens tomorrow's page right where you are, so “ask about the contract” lands on the day you'll actually need it.
A minimal starting routine
- When you sit down in the morning, write one line about what the day is for.
- Every time you switch tasks, write the time and one sentence. No standards, no formatting.
- When something is for another day, send it there (
@in Hejour) instead of trusting memory. - Don't reread daily. Let search be your memory; reread only when you need to.
That's the whole method. It survives busy weeks because a bad day still gets two lines, and two lines keep the habit alive. If you want a Mac app shaped exactly like this workflow, Hejour is a free download — every day is a page, and the pages take care of themselves.
