Success comes from failure, not from memorizing the right answers.

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 my only option, failure's not.

Do not allow yourselves to be disheartened by any failure as long as you have done your best.

We don't have to be victims of our past, that we can let go of our bitterness, and that all of us can achieve greatness.

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