They who have conquered doubt and fear have conquered failure.

I think that failure by your own standards is certainly a form of success.

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

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

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

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

I can accept failure, everyone fails at something. But I can't accept not trying.

Failure is not our only punishment for laziness there is also the success of others.

Outward failure may be a manifested variant of inward success.

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