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

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

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. 

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

Don’t hang your targets after you’re done shooting.

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

The journey of a thousand miles begins with one step. 

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

You can be shown the path, but only you can make the first step.

The bad news is time flies, the good new is that you're the pilot.

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

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