I think success has no rules, but you can learn a great deal from failure.

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

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.

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

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

Failure doesn't kill you... it increases your desire to make something happen.

Our failings sometimes bind us to one another as closely as could virtue itself.

Success needs no explanation. Failure does not have one that matters.

Success is never final, failure is never fatal. It's courage that counts.

It's how you deal with failure that determines how you achieve success.
