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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Failure is NOT your destiny. Failure is the key to success.

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

If you fail, next time fail better.

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

The wise person knows that no answer is also an answer

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

There are no shortcuts to any place worth going.

You can have results or excuses, not both

The easiest person to deceive is yourself.

Everything you want is on the other side of fear

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