Outward failure may be a manifested variant of inward success.

Failure is nature's plan to prepare you for great responsibilities.

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

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

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

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

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

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

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

There's no such thing as failure - just waiting for success.
