Failure is more frequently from want of energy than want of capital.

We climb to heaven most often on the ruins of our cherished plans, finding our failures were successes.

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.

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

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.

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

Remember that failure is an event, not a person.

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.
