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

There are no bad mistakes in maths, only discoveries.

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.

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

Success is a journey, not a destination.

Fall down seven times, stand up eight.

Try and do one thing each day that you would really rather not do.

Life is full of opportunities. With every opportunity that is missed, another one is born.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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

Time is your friend, impulse is your enemy.

If you fail, next time fail better.

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