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

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

The only real failure in life is not to be true to the best one knows.

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

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

Remember that failure is an event, not a person.

Success represents the 1% of your work which results from the 99% that is called failure.

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

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

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