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

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

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

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

I can accept failure, everyone fails at something. But I can't accept not trying.

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

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

I will not be discouraged by failure I will not be elated by success.

Success and failure are both part of life. Both are not permanent.

It's not a very high failure rate if you choose people that you really like the sound of.
