Never lose a holy curiosity. Try not to become a man of success but rather try to become a man of value. He is considered successful in our day who gets more out of life than he puts in. But a man of value will give more than he receives.
But man is a fickle and disreputable creature and perhaps, like a chess-player, is interested in the process of attaining his goal rather than the goal itself.
We learn early on that, in order to be a winner, you have to believe in yourself. You have to have the confidence to make things happen. And you have to have personal pride.
