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

The master has failed more times than the beginner has even tried

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

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

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

Failure to prepare = preparing to fail

Success is a journey, not a destination.

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. 

The journey of a thousand miles begins with one step.

The greatest mistake we make is living in constant fear that we will make one.

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

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