Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

Everything you want is on the other side of fear

Fall down seven times, stand up eight.

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

The journey of a thousand miles begins with one step. 

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

We learn more from failure than we do from success.

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

Time is your friend, impulse is your enemy.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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. 

Hard work - a two way street where you get exactly what you put in.
