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

If you're not failing every now and again, it's a sign you're not doing anything very innovative.

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

Failure is not fatal, but failure to change might be.

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

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

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

I will not be discouraged by failure I will not be elated by success.

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

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