Think Independently

🌱 Beginner★★★★★

Do your own research thoroughly before buying — no shortcut replaces understanding the actual business.

💬

Never invest in any company before you've done the homework on the company's earnings prospects, financial condition, competitive position, and expansion plans.

— *One Up On Wall Street*，1989

🏠 Everyday Analogy

Just as one must inspect a property in person, examine its layout, and understand the surrounding amenities before buying a house, investors must personally research a company's financial condition, competitive position, and growth prospects before investing—rather than blindly trusting what a sales agent says.

📖 Core Interpretation

Do your own research; do not blindly follow experts or popular recommendations.
💎 Key Insight：Lynch spent hours reading annual reports, visiting stores, and talking to management for every stock he bought. He never relied on tips, rumors, or analyst recommendations as substitutes for firsthand research. Understanding a company's earnings trajectory, competitive position, balance sheet strength, and expansion plans gives you the conviction to hold through volatility and the clarity to sell when the story changes.
