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.

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

Failure is simply a few errors in judgment, repeated every day.

Failure is the condiment that gives success its flavor.

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

Once you can accept failure, you can have fun and success.

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 comes when people act together failure tends to happen alone.

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

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