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. 

Patience is when you’re supposed to get mad, but you choose to understand

You cannot escape the responsibility of tomorrow by evading it today

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

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

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

The road to success is like a staircase. If you want to succeed, double your failure rate

We learn more from failure than we do from success.

It doesn’t matter where you start, it matters how you end

There are no bad mistakes in maths, only discoveries.

Procrastination is the thief of time and the enemy of success.

Hope might be a good breakfast, but it makes a very poor dinner

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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