How do I practice trigger condition action?

The most direct way to practice trigger condition action is through a focused exercise: Pick one recurring decision you make on autopilot — what to eat for lunch, whether to check your phone when it buzzes, how to respond when a meeting runs over. Decompose it into its three components: (1) What triggers it? Name the specific situational cue. (2) What condition validates it? What must be true for you to proceed? (3) What action do you take? Write it as a single if-when-then statement: 'When [trigger], if [condition], then [action].' You have now reverse-engineered one of your default agents.

Common pitfall: Building agents with missing components. A trigger without a condition fires indiscriminately — you respond to every notification regardless of context. A condition without a trigger never activates — you have a brilliant rule that waits forever for a cue you never specified. An action without a trigger and condition is just a behavior you perform randomly. Most broken personal systems fail because one of the three components is implicit, vague, or missing entirely.

This practice connects to Phase 21 (Agent Fundamentals) — building it as a repeatable habit compounds over time.
