Confidence

Somehow I can't believe that there are any heights that can't be scaled by a man who knows the secrets of making dreams come true. This special secret - curiosity, confidence, courage, and constancy, and the greatest of all is confidence. When you believe in a thing, believe in it all the way, implicitly and unquestionable.  - Walt Disney

Believe in yourself, believe in your dreams!  Realize that you don't have to look outside yourself for strength...it is there all the time.
