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.

They who have conquered doubt and fear have conquered failure.

Defeat is not the worst of failures. Not to have tried is the true failure.

Do not let your ambitions become a sanctuary for your failures.

There is no loneliness greater than the loneliness of a failure. The failure is a stranger in his own house.

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

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

Failure doesn't kill you... it increases your desire to make something happen.

Failure is the condiment that gives success its flavor.

We climb to heaven most often on the ruins of our cherished plans, finding our failures were successes.
