It is often the failure who is the pioneer in new lands, new undertakings, and new forms of expression.

Often the difference between a successful man and a failure is not one's better abilities or ideas, but the courage that one has to bet on his ideas, to take a calculated risk, and to act.

Failure is the condiment that gives success its flavor.

I have always been pushed by the negative. The apparent failure of a play sends me back to my typewriter that very night, before the reviews are out. I am more compelled to get back to work than if I had a success.

But while success and failure depend on conditions, the mind neither waxes nor wanes.
