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

Failure is simply a few errors in judgment, repeated every day.

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

Defeat is not the worst of failures. Not to have tried is the true failure.

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

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

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

It's fine to celebrate success but it is more important to heed the lessons of failure.

You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.

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