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

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

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

Remember that failure is an event, not a person.

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

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

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

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

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

We may be personally defeated, but our principles never!
