We all see this amply displayed by some professional athletes. The dread of success is especially felt in female athletes, some of whom are raised to think aggression is not nice. For many children raised religiously winning implies selfish striving which is considered sinful. Occasionally a child raised in the lower class who later becomes a star with great fame and wealth has a sense of dread that they are leaving their families behind. This explains why you so often hear professional athletes say their true desire is to buy their mothers a home with the money they make.
Success can bring with it great guilt.
The recent near disqualification of a pro golfer at a Tour event may have something to do with the dread of success. He had already won three tournaments this year. It was reported that before the tournament he had lost two close friends to sudden death. During the event he was nearly disqualified twice, once due to almost missing a tee time and once by marking his ball on the 72nd green a failing to replace it properly. If he had signed his scorecard without the score adjustment and the two shot penalty he would have been disqualified.
