"Most people who do a lot of exercise, particularly in the form of competitive athletics, have unneurotic, extraverted, optimistic personalities to begin with. (Marathon runners are exceptions to this.)"

Potential does not always ensure success. The greatest players have not always been the most endowed. In athletics, we often hear the phrase, "He has the will to win". I think this is wrong. We can have the greatest will to do well. But unless we have prepared, it is of little use. Really, it should be the "will to prepare". Those who succeed have this will, whether it be in athletics, whether it be in school, whether it be in their chosen vocation, whether it be on a mission, or in almost any other phase of their life.
