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

I don't believe in failure. It is not failure if you enjoyed the process.

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

Success and failure are both part of life. Both are not permanent.

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

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

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

I think that failure by your own standards is certainly a form of success.

Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

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