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

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 stumbling from failure to failure with no loss of enthusiasm.

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

I firmly believe that unless one has tasted the bitter pill of failure, one cannot aspire enough for success.

Failure comes from ego, greed, envy, fear, imitation. I have success not because I am smart, but because I am rational.
