Evergreen notes

A note about a kind of note. Recursion intentional.

June 22, 2025 tools for thought

An evergreen note is a single, well-titled, atomic unit of belief that you intend to revise rather than archive. It earns its keep over time: the longer you have it, the more places it gets pointed at, the more useful it becomes.

The two properties I find most useful in practice:

  • Atomicity. A note holds one idea. If two ideas live in one note, one of them is sleeping under the other.
  • Concept-not-event titling. The title is the idea, not the occasion of writing. “Reading on paper vs. screen” — yes. “Thoughts from train ride” — no.

This idea comes from Andy Matuschak. I disagree with him on one small thing, captured in Notes vs. marks: not every annotation should aspire to evergreen status. Some marks are good because they are ephemeral.
