How do I practice compound ideas?

The most direct way to practice compound ideas is through a focused exercise: Take one belief you currently hold about your work, career, or a project — something you'd state as a single sentence. Write it down. Now decompose it: list every assumption that must be true for that sentence to hold. Aim for at least four. For each assumption, ask: 'Have I actually tested this, or am I treating it as given?' Circle the untested ones. You've just mapped the hidden dependencies in a compound idea.

Common pitfall: Decomposing the idea intellectually but continuing to act on it as a monolith. You'll know this is happening when someone challenges one part of your plan and you defend the whole thing — because in your mind, it's still one idea. The decomposition only works if each piece gets evaluated independently.

This practice connects to Phase 2 (Atomicity and Decomposition) — building it as a repeatable habit compounds over time.
