How do I practice schema inventory?

The most direct way to practice schema inventory is through a focused exercise: Set a 30-minute timer. List every schema you can identify that governs how you make decisions in your primary domain — career, relationships, health, money, or craft. For each one, write: (1) the schema as a single sentence, (2) where you acquired it, (3) when you last tested or updated it, and (4) your current confidence level (high/medium/low). Aim for at least 15 entries. When you finish, look at how many you rated high-confidence but have never actually tested. That gap between confidence and verification is the entire reason inventories matter.

Common pitfall: Creating the inventory once and treating it as done. A schema inventory is not a one-time snapshot — it is a living registry. Schemas you don't notice today will surface next month. Schemas you list today will change. The failure mode is turning a dynamic tool into a static artifact that gathers dust in a notebook. If you haven't touched the inventory in 30 days, it's already obsolete.

This practice connects to Phase 17 (Meta-Schemas) — building it as a repeatable habit compounds over time.
