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

Do what you have always done and you will always be what you have always been

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

Knowledge is of no value unless you put it into practice.

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.

It doesn’t matter where you start, it matters how you end

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

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

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

If you want to succeed, double your failure rate.

Patience is when you’re supposed to get mad, but you choose to understand

You can be shown the path, but only you can make the first step.

We learn more from failure than we do from success.

Hope might be a good breakfast, but it makes a very poor dinner

Try and do one thing each day that you would really rather not do.
