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

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

Defeat is not the worst of failures. Not to have tried is the true failure.

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

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

Failure is what we're all running from, we're always running toward success with failure at our back.

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

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

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

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