Hard work beats talent when talent doesn't work hard.

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. 

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

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

We learn more from failure than we do from success.

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

The road to success is like a staircase. If you want to succeed, double your failure rate

I think, therefore I am.

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

Don’t practice until you get it right, practice until you can’t get it wrong.

The journey of a thousand miles begins with one step.

A book a day keeps the stupidity away.

Life is full of opportunities. With every opportunity that is missed, another one is born.
