It is not a disgrace to fail. Failing is one of the greatest arts in the world.

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.

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

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

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

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.

Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.

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

You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.
