How do I practice personal dashboard?

Build a minimal personal dashboard this week. Choose one metric from each of three life domains (body, mind, relationships — or your own categories). Track them daily for seven days in a single view — a spreadsheet row, a Notion page, or a paper grid. At the end of the week, look at all three together and write one sentence about what the combined picture tells you that no single metric would have revealed alone.

Common pitfall: Treating the dashboard as a scoreboard instead of a mirror. When you optimize for the numbers rather than the reality the numbers represent, you invoke Goodhart's law: the measure ceases to be a good measure. You'll know this is happening when you feel anxiety about a metric dropping rather than curiosity about what changed.

This practice connects to Externalization Mastery — building it as a repeatable habit compounds over time.
