Success is not final, failure is not fatal.  It is the courage to continue that counts.

No one starts out on top. You have to work your way up.

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

We all make mistakes. What matters is how we choose to move forwards from them.

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.

Failure to prepare = preparing to fail

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

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. 

You cannot escape the responsibility of tomorrow by evading it today

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

Success is a journey, not a destination.

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

We learn more from failure than we do from success.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

There are no bad mistakes in maths, only discoveries.
