Most note-taking advice obsesses over tools and templates. But across a century of research and practice, only three principles reliably separate notes that get used from notes that get archived:
The three principles
1. Your own words beat transcription. Copying preserves the source; rephrasing builds the understanding. If you can't say it in your own words, you've found exactly the thing you haven't learned yet — which is the most valuable thing a note can tell you.
2. Capture speed beats capture quality. A rough note taken in two seconds outperforms a beautiful note you never started, because forgetting begins within minutes. Lower the cost of writing things down to almost nothing (one tap, ideally) and clean up later — or never.
3. A brief review beats a big archive. Notes pay off when they come back to you. Two minutes of review the same day, a skim at the end of the week — that tiny loop is where retention actually comes from.
Guides by situation
- How to organize your notes so you actually use them — the calm system: capture first, organise lightly, let search and AI do the filing.
- How to take meeting notes — decisions, actions, and questions; not transcripts.
- More on the way: lecture notes, reading notes, notes for ADHD, studying from notes — this section grows week by week.
Match the notes to the moment
A meeting, a lecture, and a shower thought need different levels of structure — that's what the note-taking methods section is for. But they all share the same first step: the thought has to land somewhere instantly, or it's gone. Students juggling five courses feel this hardest (we wrote about that), but it's just as true in back-to-back meetings.
For the science underneath these habits, start with memory & focus.
