📖Peter Lynch
Corrections Are Normal
Market declines are a normal part of investing.
A decline of 10% is a correction, a decline of 25% is a bear market, and a decline of 50% happens roughly once every generation. None of these should cause panic.
🏠 Everyday Analogy
📖 Core Interpretation
Peter Lynch advocates a repeatable process: define criteria, execute consistently, and review decisions against evidence. Process quality drives outcome consistency.
💎 Key Insight：Understanding historical frequency of declines prevents panic.

❓ 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
