How to start a decision journal
A decision journal is the single highest-leverage habit for improving your judgment. This is the 7-step setup we recommend — no apps required, but a system you'll actually keep.
1. Pick one place to write
Choose a single home for your entries — a notebook, a notes app, or Choice Map. Friction kills journaling habits; if you can't open it in under ten seconds, you won't.
2. Capture the decision, not the outcome
Write what you decided, what you expected to happen, and the alternatives you rejected. Outcomes come later — the goal now is to freeze your reasoning before hindsight rewrites it.
3. Note the confidence and context
Rate how confident you were (1–10) and jot the context: your mood, the constraints, the deadline. These signals are what separate skill from luck when you review later.
4. Set a review date
Every entry needs a future check-in — usually 30, 90, or 180 days out. Without a scheduled review, the journal becomes a graveyard of forgotten promises.
5. Review honestly
On the review date, score the outcome and write one sentence on what surprised you. Don't grade yourself on the result alone — grade the process that produced it.
6. Tag the patterns
After ten or so reviews, tag entries by theme: career, money, relationships, health. Patterns emerge quickly — the categories where you systematically over- or under-estimate yourself.
7. Keep it small
Five minutes per entry. One paragraph. The journal you actually keep beats the perfect one you abandon in three weeks.
