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

I think that failure by your own standards is certainly a form of success.

Failure is nature's plan to prepare you for great responsibilities.

Outward failure may be a manifested variant of inward success.

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

Failure is unimportant. It takes courage to make a fool of yourself.

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

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

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

Failure seldom stops you. What stops you is the fear of failure.
