Success is a journey, not a destination.

Fall down seven times, stand up eight.

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. 

There are no bad mistakes in maths, only discoveries.

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

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Shoot for the moon and even if you miss you’ll land among the stars/

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

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

A book a day keeps the stupidity away.

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