Courage and Self-Confidence Quotes

Somehow I can't believe there are many heights that can't be scaled by a man who knows the secret of making dreams come true. This special secret, it seems to me, can be summarized in four C's. They are Curiosity, Confidence, Courage, and Constancy. And the greatest of these is Confidence. When you believe a thing, believe it all over, implicitly and unquestioningly.
Walt Disney

It is only necessary to have courage, for strength without self-confidence is useless.
Giacomo Casanova

Without courage, wisdom bears no fruit.
Baltasar Gracian
