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

Everything you want is on the other side of fear

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

We learn more from failure than we do from success.

The bad news is time flies, the good new is that you're the pilot.

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.

The journey of a thousand miles begins with one step. 

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

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

It is never too late to become what you might have been

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

I can is 100 times more important than IQ.
