Understand Before Investing

🌱 Beginner★★★★★

Only invest in what you can explain simply.

💬

Never invest in a business you cannot explain in simple terms. If you can't describe why a company is valuable, you don't understand it well enough to own it.

❓ 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
