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

They who have conquered doubt and fear have conquered failure.

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

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

Failure seldom stops you. What stops you is the fear of failure.

The season of failure is the best time for sowing the seeds of success.

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

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