How do I practice capture tools?

The most direct way to practice capture tools is through a focused exercise: Map every context where you regularly think: desk, commute, walking, shower, bed, meetings, gym, cooking. For each one, write down your current capture tool and how many seconds it takes to go from thought to externalized text (or voice). Any context over 10 seconds is a leak. Any context with no tool is a hole. Fix the worst one today — install a widget, place a waterproof notepad, put index cards in your jacket pocket.

Common pitfall: Choosing a capture tool because it's powerful rather than because it's present. The person who picks Obsidian as their only capture tool and leaves it on their laptop will lose every thought they have away from their desk. Capability is irrelevant if the tool isn't within arm's reach when the thought arrives. Optimize for proximity first, features second.

This practice connects to Phase 3 (Capture Systems) — building it as a repeatable habit compounds over time.
