The most important of my discoveries have been suggested to me by my failures.

Failure seldom stops you. What stops you is the fear of failure.

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

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

Admitting failure is quite cleansing, but never - pleasurable.

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

My great concern is not whether you have failed, but whether you are content with your failure.

We have forty million reasons for failure, but not a single excuse.

I think success has no rules, but you can learn a great deal from failure.

Defeat is not the worst of failures. Not to have tried is the true failure.
