I will not be discouraged by failure I will not be elated by success.

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

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

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

We may be personally defeated, but our principles never!

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

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

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

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

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