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

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

Failure to prepare = preparing to fail

A hero is no braver than an ordinary man, but he is braver five minutes longer.

We learn more from failure than we do from success.

Fall down seven times, stand up eight.

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

A book a day keeps the stupidity away.

I can is 100 times more important than IQ.

I think, therefore I am.

The temptation to quit will be the greatest when you are about to succeed

It doesn’t matter where you start, it matters how you end

Don’t compare yourself to others. Compare yourself to the person you were yesterday.
