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

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

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

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.

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

We have forty million reasons for failure, but not a single excuse.

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

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

The great question is not whether you have failed, but whether you are content with failure.
