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

Failure doesn't kill you... it increases your desire to make something happen.

Remember that failure is an event, not a person.

Failure is unimportant. It takes courage to make a fool of yourself.

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

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

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

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.

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

I can accept failure, everyone fails at something. But I can't accept not trying.
