I think that failure by your own standards is certainly a form of success.

Success consists of going from failure to failure without loss of enthusiasm.

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

Failure is what we're all running from, we're always running toward success with failure at our back.

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

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

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

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

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

Outward failure may be a manifested variant of inward success.
