The Judgment Journal

Most people make 100 decisions a year and learn from zero. What if you could compound your judgment the way you compound interest?

The Decision Journal: before deciding, write what you're deciding, your expected outcome, your reasoning, and your confidence level 1–10.

After 3–6 months, return and review. What actually happened? Why were you right or wrong? What would you do differently now?

A venture firm tracked every investment decision for 5 years. They discovered they were consistently overconfident in their own industry expertise.

The pitfall: writing only successes in your journal. Document losses and near-misses — that's where the real calibration data lives.

The journal doesn't judge you — it teaches you. Over time, you stop being surprised by your own patterns. That's mastery.

You now know: most people make 100 decisions a year and learn from zero. The journal changes that. Let's make your first entry right now.

Today's exercise: make your first Decision Journal entry RIGHT NOW for a real decision you're currently facing. Four parts, five minutes.

Write: (1) The decision you're facing. (2) Your expected outcome. (3) Your reasoning in 3 sentences max. Be specific, not optimistic.

Then write: (4) Your confidence level 1–10. If it's above 8, ask yourself: what would have to be true for this to go wrong?

Now: set a calendar reminder for 3 months from today labeled 'Decision Journal Review.' That one click closes the learning loop.

The compass reflects itself now — past decisions teaching future ones. Your judgment loop has officially begun.
