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

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

You can have results or excuses, not both

Skills are built not born.

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

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

Shoot for the moon and even if you miss you’ll land among the stars/

Don’t practice until you get it right, practice until you can’t get it wrong.

There are no bad mistakes in maths, only discoveries.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

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

If you fail, next time fail better.

Don’t be afraid to work hard and find out how good you can really be.

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