Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

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

You can have results or excuses, not both

Don’t be afraid to work hard and find out how good you can really be.

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

You cannot start the next chapter of your life if you keep re-reading the last one.

He who has begun his task is half-way done. Have the courage to begin!

If you want to succeed, double your failure rate.

If you fail, next time fail better.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

No one starts out on top. You have to work your way up.

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

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

It is never too late to become what you might have been
