Avoid Emotional Decisions

🌱 Beginner★★★★★

Emotional investing is the fastest path to financial ruin.

💬

If you cannot control your emotions, you cannot control your money.

— Multiple Interviews，2008

🏠 Everyday Analogy

Investing is like driving; emotional decision-making is akin to drunk driving. Slamming the brakes in fear can lead to rear-end collisions, while stomping on the accelerator in greed risks crashing into a wall. Only by staying clear-headed and rational, steadily advancing along the planned route, can one safely reach the destination of wealth.

📖 Core Interpretation

Emotion is the greatest enemy of investment. Fear leads to selling at lows, while greed leads to buying at highs.
💎 Key Insight：Fear and greed drive the market cycle, and most investors are their prisoners. Fear causes selling at bottoms; greed causes buying at tops. The antidote isn't suppressing emotions — it's having a pre-set investment framework that removes emotion from decisions. Write your buy/sell criteria before you invest, then follow the plan mechanically.

🎙️ Master's Voice

If you cannot control your emotions, you cannot control your money.
During the 2008 crisis, many investors sold at the bottom in March 2009, locking in 50%+ losses. They then missed the recovery. Studies show the average investor earns far less than the market due to emotional timing. Emotional investing destroys more wealth than bad analysis.
