How do I practice override inheritance?

The most direct way to practice override inheritance is through a focused exercise: Open your knowledge system and find a category, tag, or folder where at least one item doesn't fully belong — it inherited assumptions from its parent that don't hold. Write a one-sentence override statement on that item: 'Unlike [parent category], this item [specific difference].' Notice how the override makes the exception legible instead of silently confusing your future self.

Common pitfall: You notice exceptions but leave them implicit, trusting your memory to handle the special cases. Over time, the exceptions multiply. You stop trusting the parent category because too many children violate its assumptions, but you never articulate which assumptions break or why. The hierarchy becomes decoration — technically present but functionally ignored.

This practice connects to Phase 14 (Hierarchy and Nesting) — building it as a repeatable habit compounds over time.
