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

You become strong by defying defeat and by turning loss and failure into success.

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.

Great success always comes at the risk of enormous failure.

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.

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