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 WaitleyThe first best-kept secret of total success is that we must feel love inside ourselves before we can give it to others.
Denis WaitleyWhen you make a mistake or get ridiculed or rejected, look at mistakes as learning experiences, and ridicule as ignorance. Look at rejection as part of one performance, not as a turn down of the performer.
