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

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

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. 

There are no shortcuts to any place worth going.

The journey of a thousand miles begins with one step.

The greatest enemy to human potential is your comfort zone

Success is a journey, not a destination.

Failure to prepare = preparing to fail

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

You can be shown the path, but only you can make the first step.

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.
