❓ Why It Matters
Without business-quality filters, investors drift toward stories rather than economics. Durable cash generation is what supports long-term valuation.
🎯 How to Practice
Use a checklist covering moat, management, unit economics, and capital allocation; track long-term cash generation instead of quarter-to-quarter noise.
🎙️ Master's Voice
Do not fall in love with your investments.
Neff sold positions when they reached fair value, even if he loved the company. Emotional attachment to investments leads to holding too long. Discipline requires selling when the price is right.
