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.
A winner concentrates on that which is goal achieving rather than tension relieving.
We don't get what we want, we get what we expect.
Don't 'take care', take a risk!
Don't be a time manager, be a priority manager.
You always project on the outside how you feel on the inside.
