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.

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

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

They who have conquered doubt and fear have conquered failure.

We have forty million reasons for failure, but not a single excuse.

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

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

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

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

Failure is not fatal, but failure to change might be.
