The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

Instead of finding reasons why you can't, find reasons why you can.

The easiest person to deceive is yourself.

There is no elevator to success, you have to take the stairs.

There are no bad mistakes in maths, only discoveries.

In order to become better than anybody else you must first become better than yourself.

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

You cannot start the next chapter of your life if you keep re-reading the last one.

We learn more from failure than we do from success.

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

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

Success is the sum of small repeated efforts, day in and day out.

Failure is not the opposite of success, it is part of the success.

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. 

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