"And when the market goes your way you become fearful that the next day will take away your profit, and you get out-too soon.

"Fear keeps you from making as much money as you ought to. The successful trader has to fight these two deep-seated instincts. He has to reverse what you might call his natural impulses. Instead of hoping he must fear; instead of fearing he must hope. He must fear that his loss may develop into a much bigger loss, and hope that his profit may become a big profit. It is absolutely wrong to gamble in stocks the way the average man does."
