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

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

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

Success can never happen without the journey (struggle).

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

Just stick with it, what seems hard now will one day be your warm up.

The master has failed more times than the beginner has even tried

Instead of finding reasons why you can't, find reasons why you can.

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

There are no shortcuts to any place worth going.

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

I can is 100 times more important than IQ.

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