Many of life's failures are people who did not realize how close they were to success when they gave up.

The only real failure in life is not to be true to the best one knows.

Show me a thoroughly satisfied man and I will show you a failure.

I have tried 99 times and have failed, but on the 100th time came success.

Great success always comes at the risk of enormous failure.

Failure is unimportant. It takes courage to make a fool of yourself.
