Realizing graveyard of good intentions is not that valuable is one of the most important things that we have to learn. Best to just cut it and work on what is ahead.
Stuff that is relevant for things I am currently busy with are recent so like last couple weeks. Stuff that I don’t remember touching in those weeks gets deleted.
For the non-note stuff, do you have a “recently touched” equivalent, or do you rely on different rules (e.g. archiving/search for email, starred threads for chat, etc.)?
