The winner glories in the good; the whiner majors in the mediocre. Winners' thinking processes differ from other people's. As part of their normal, moment-to-moment stream of consciousness, winners think constantly in terms of I can and I will. Losers concentrate their waking thoughts on what they should have done would have done what they can't do. When the mind's self-talk is positive, performance is more likely to be successful.
The huge majority of our negative doubts and fears are imaginary or beyond our control.
