An archive becomes a memory the day you start interrogating it. Most people never do, because they assume the answer would take an hour of scrolling. With semantic search and chat over your own notes, these ten questions take a minute each—and several of them are worth asking regularly.
The ten questions
Each of these works because it asks about something your history actually witnessed: decisions, promises, opinions, and repetition.
- What did I decide about X—and when exactly?
- What have I promised, and to whom, that is still open?
- What is still owed to me that I have stopped tracking?
- What was I worried about six months ago—and did it happen?
- Which ideas keep coming back in different words?
- What did person N and I agree on last time we spoke?
- What did that repair, service, or subscription actually cost?
- Why did I choose this option over the alternative?
- What did I postpone ‘until later’—is later now?
- How has my thinking about Z changed over the past year?
Judge answers by their evidence
A good answer to any of these shows its sources: the notes it drew from, with dates and excerpts. If an answer arrives without evidence, treat it as a hypothesis and open the underlying notes before acting.
Chronology is half the answer
Questions about decisions and opinions are really questions about sequence. Insist on knowing which note is most recent; an old enthusiasm quoted without its later reversal is worse than no answer.
Make one of them a habit
Pick the question that hurts most when unanswered—for most people it is the one about open promises—and ask it every week. One recurring question turns an archive into a practice.
Your history already contains the answers. The skill is asking specific questions and refusing any answer that cannot show where it came from.
