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

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.

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

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

Don't fear failure, fear being in the same exact same place next year as you are now.

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

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

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

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

You're not in competition with anyone but yourself. Outdo your past, not other people.

Skills are built not born.

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

If you fail, next time fail better.

Hard work beats talent when talent doesn't work hard.
