Success is not final, failure is not fatal: it is the courage to continue that counts.

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.

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

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

Failure is the condiment that gives success its flavor.

Outward failure may be a manifested variant of inward success.

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

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

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.
