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

Once you can accept failure, you can have fun and success.

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

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

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

We may be personally defeated, but our principles never!

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 more frequently from want of energy than want of capital.

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