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.

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

Success and failure are both part of life. Both are not permanent.

I think that failure by your own standards is certainly a form of success.

Success needs no explanation. Failure does not have one that matters.

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

Success is never final, failure is never fatal. It's courage that counts.

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

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

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