Capture one useful fragment
Save one idea today with context: source, why it matters, and where it might be used.
Distill one old note
Open an existing note and reduce it to the few lines future-you would need to act on it.
Move one note to action
Use a saved note in a project, message, decision, outline, or plan. Expression keeps the system alive.
