They who have conquered doubt and fear have conquered failure.

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

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

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

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

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

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

It's how you deal with failure that determines how you achieve success.

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

Admitting failure is quite cleansing, but never - pleasurable.
