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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Practice like you’ve never won. Perform like you’ve never lost.

Don’t hang your targets after you’re done shooting.

You can have results or excuses, not both

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

You cannot escape the responsibility of tomorrow by evading it today

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

Procrastination is the thief of time and the enemy of success.

It always seems impossible until it's done.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
