❓ 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.

⚠️ Common Pitfalls

Buying narratives instead of cash-generating economics
Overreacting to short-term operating noise
Ignoring management quality and capital allocation
