The confidence you need is belief in your potential. If you see world-class potential in yourself, you'll put in the effort. If you don't see the potential, you won't put in the effort and you'll wait for the performance, and the performance always follows the belief in self.
Denis WaitleyOn our track to success, we have to fight the tendency to look at others and see how far they've come. The only thing that counts is how we use the potential we possess and that we run our race to the best of our abilities.
