Don't take 'no' for an answer, never submit to failure. Do not be fobbed off with mere personal success or acceptance. You will make all kinds of mistakes, but as long as you are generous and true, and also fierce, you cannot hurt the world or events.

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

The people who are crazy enough to think they can change the world are the ones who do.

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

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

Great success always comes at the risk of enormous failure.
