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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

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.

Hard work beats talent when talent doesn't work hard.

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

Pure mathematics is in its way, the poetry of logical ideas.

Fall down seven times, stand up eight.

Failure to prepare = preparing to fail

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

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

I think, therefore I am.

There are no bad mistakes in maths, only discoveries.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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