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

We learn more from failure than we do from success.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

If you fail, next time fail better.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Fall down seven times, stand up eight.

I have not failed, I've just found 10,000 ways that won't work.

A book a day keeps the stupidity away.

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. 

Everything you want is on the other side of fear

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.

Don’t practice until you get it right, practice until you can’t get it wrong.
