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.

I was relentless, even in the face of total lack of encouragement, because much more often than you'd think, sheer persistence is the difference between success and failure.

Great success always comes at the risk of enormous failure.

Success is stumbling from failure to failure with no loss of enthusiasm.

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

I have tried 99 times and have failed, but on the 100th time came success.
