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

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

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

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

Success represents the 1% of your work which results from the 99% that is called failure.

Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

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

You cannot climb the ladder of success dressed in the costume of failure.

Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.

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