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

There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.

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

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

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

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

I think success has no rules, but you can learn a great deal from failure.

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

Failure is not fatal, but failure to change might be.

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