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's not necessary to fear the prospect of failure but to be determined not to fail.

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

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

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

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

Failure is the condiment that gives success its flavor.

Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.

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

It's not a very high failure rate if you choose people that you really like the sound of.
