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

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

Enjoy failure and learn from it. You can never learn from success.

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

Do not fear mistakes. You will know failure. Continue to reach out.

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.

Outward failure may be a manifested variant of inward success.

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

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