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

Leaders, true leaders, take responsibility for the success of the team and understand that they must also take responsibility for the 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 comes from failure, not from memorizing the right answers.

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.
