When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

We learn more from failure than we do from success.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

Start, struggle, fail, fix and learn. Repeat.

Your attitude is everything. Pick a good one.

In order to become better than anybody else you must first become better than yourself.

Instead of finding reasons why you can't, find reasons why you can.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Your limitation - its only your imagination.

Don’t practice until you get it right, practice until you can’t get it wrong.

Mistakes have the power to turn you into something better than you were before.

Pure mathematics is in its way, the poetry of logical ideas.

Nobody said it’d be easy, they just promised it would be worth it.
