Duan Yongping highlights that many investment mistakes are psychological, not analytical. Managing behavior under stress is as important as finding ideas. Key insight: Emotional control is the foundation of investment success. Emotions in markets are like steering on a wet road: the harder you jerk the wheel, the more likely you lose control.
