They who have conquered doubt and fear have conquered failure.

Failure is more frequently from want of energy than want of capital.

Do not fear mistakes. You will know failure. Continue to reach out.

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

The great question is not whether you have failed, but whether you are content with failure.

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

Success is never final, failure is never fatal. It's courage that counts.

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

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

I can accept failure, everyone fails at something. But I can't accept not trying.
