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.

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

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

Everything you want is on the other side of fear

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

If you want to succeed, double your failure rate.

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

Success can never happen without the journey (struggle).

Everything that happens was once a dream.

Dreams don't work unless you do.

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

Skills are built not born.
