Knowledge is of no value unless you put it into practice.

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.

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

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

It always seems impossible until it's done.

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

Hard work - a two way street where you get exactly what you put in.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

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

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

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

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 think, therefore I am.
