📖Li Lu
Intellectual Honesty
Intellectual honesty about knowledge limits is the beginning of investment wisdom.
Be honest about what you know and dont know. Admitting ignorance is the beginning of wisdom.
🏠 Everyday Analogy
📖 Core Interpretation
Li Lu advocates a repeatable process: define criteria, execute consistently, and review decisions against evidence. Process quality drives outcome consistency.
💎 Key Insight：Li Lu believes the most dangerous phrase in investing is "I know." Admitting what you don't know is more important than claiming expertise. Overconfidence leads to ventures outside your competence and mistakes from incomplete information. The best investors maintain a beginner's mind, constantly questioning assumptions and seeking contrary evidence. This humility prevents costly errors from overconfidence and keeps the mind open to new information. Saying "I don't know" allows you to avoid investments you don't understand rather than pretending knowledge you don't possess.

🎙️ Master's Voice
Compound knowledge like compound interest. Both grow exponentially over time.
Li Lu spends hours every day reading and learning. He views knowledge acquisition as compounding—each new insight builds on previous ones. After decades, this creates an enormous informational advantage.
