❓ 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
