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

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

The road to success is like a staircase. If you want to succeed, double your failure rate

If you can understand just one thing thoroughly, then you will understand everything.

A book a day keeps the stupidity away.

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

Success is a journey, not a destination.

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

There are no shortcuts to any place worth going.

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. 

It is never too late to turn an unproductive day into a productive one.

Failure to prepare = preparing to fail

If you want to succeed, double your failure rate.

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

Failure is not the opposite of success, it is part of the success.
