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 fine to celebrate success but it is more important to heed the lessons of failure.

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

Success is not final, failure is not fatal: it is the courage to continue that counts.

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

Don't be afraid of missing opportunities. Behind every failure is an opportunity somebody wishes they had missed.

The only real failure in life is not to be true to the best one knows.

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

Every adversity, every failure, every heartache carries with it the seed on an equal or greater benefit.

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