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. 

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

I can is 100 times more important than IQ.

Success is a journey, not a destination.

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

Failure to prepare = preparing to fail

Do what you have always done and you will always be what you have always been

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

I think, therefore I am.

Failure is not the opposite of success, it is part of the success.

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

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

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

Never underestimate the importance of small steps. small steps = big changes. 

Fall down seven times, stand up eight.
