❓ Why It Matters

Without process, there is no reliable feedback loop. Structured execution and review improve decision quality over time.

🎯 How to Practice

Run a decision loop of research, thesis, execution, and post-mortem; document assumptions and update playbooks with evidence, not hindsight bias.

⚠️ Common Pitfalls

Having opinions without execution criteria
Reviewing outcomes but not decisions
Abandoning rules during volatility spikes
