Start, struggle, fail, fix and learn. Repeat.

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

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

Tough times never last, but tough people do.

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

If you want to succeed, double your failure rate.

We learn more from failure than we do from success.

There is no elevator to success, you have to take the stairs.

Knowledge is of no value unless you put it into practice.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

No one starts out on top. You have to work your way up.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Success is a journey, not a destination.

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 think, therefore I am.
