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. 

The master has failed more times than the beginner has even tried

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

If you fail, next time fail better.

The greatest enemy to human potential is your comfort zone

Procrastination makes easy things hard and hard things harder.

There are no bad mistakes in maths, only discoveries.

Dreams don't work unless you do.

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

Go as far as you can see, when you get there, you’ll be able to see further

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

GCSE and A Level Maths are a marathon not a sprint

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Start, struggle, fail, fix and learn. Repeat.

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