Don't fear failure, fear being in the same exact same place next year as you are now.

The journey of a thousand miles begins with one step.

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

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

Nobody said it’d be easy, they just promised it would be worth it.

A book a day keeps the stupidity away.

It is never too late to turn an unproductive day into a productive one.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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. 

We learn more from failure than we do from success.

Skills are built not born.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

I think, therefore I am.

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.
