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

They who have conquered doubt and fear have conquered failure.

Success consists of going from failure to failure without loss of enthusiasm.

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

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

Failure is the condiment that gives success its flavor.

It's how you deal with failure that determines how you achieve success.

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

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.

Failure doesn't kill you... it increases your desire to make something happen.
