They who have conquered doubt and fear have conquered failure.

I will not be discouraged by failure I will not be elated by success.

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

You cannot climb the ladder of success dressed in the costume of failure.

Enjoy failure and learn from it. You can never learn from success.

Success is not final, failure is not fatal: it is the courage to continue that counts.

Failure is the condiment that gives success its flavor.

Remember that failure is an event, not a person.

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

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