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.

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.

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

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

Remember that failure is an event, not a person.

I don't believe in failure. It is not failure if you enjoyed the process.

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

Failure is what we're all running from, we're always running toward success with failure at our back.

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

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