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

We climb to heaven most often on the ruins of our cherished plans, finding our failures were successes.

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

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

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.

Remember that failure is an event, not a person.

Success needs no explanation. Failure does not have one that matters.

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

It's not necessary to fear the prospect of failure but to be determined not to fail.

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