You can't win 'til you're not afraid to lose.

I never lose. I either win or learn.

Trust me I never lose. Either I win or learn from it.

The barrier to success is not something which exists in the real world; it is composed purely and simply of doubts about ability.

Circumstances-what are circumstances? I make circumstances.

The greatest pleasure I've had is trying to do something that everybody says could not be done.
