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

Many of life's failures are people who did not realize how close they were to success when they gave up.

You build on failure. You use it as a stepping stone. Close the door on the past. You don't try to forget the mistakes, but you don't dwell on it. You don't let it have any of your energy, or any of your time, or any of your space.

Show me a thoroughly satisfied man and I will show you a failure.

I have not failed. I've just found 10,000 ways that won't work.

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