How do I practice schema debt?

The most direct way to practice schema debt is through a focused exercise: Pick one domain where you make regular decisions: your career, your health, a technical system you manage. Write down the mental model you currently operate from. Now mark every element that hasn't been verified in the last six months. Count the unverified elements. That count is a rough measure of your schema debt in that domain.

Common pitfall: Acknowledging that your schema is outdated while continuing to act on it anyway. This is the most common failure — you know the map is wrong, you tell yourself you'll update it 'when things settle down,' and meanwhile every decision compounds the cost. Awareness without action is not progress; it is cognitive dissonance wearing a productivity mask.

This practice connects to Phase 16 (Schema Evolution) — building it as a repeatable habit compounds over time.
