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.

Great success always comes at the risk of enormous failure.

I've often felt there might be more to be gained by studying business failures than business successes.

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

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