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

There are no bad mistakes in maths, only discoveries.

If you fail, next time fail better.

Skills are built not born.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Lose an hour in the morning and you will spend all day looking for it.

Dreams don't work unless you do.

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

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

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.

He who has begun his task is half-way done. Have the courage to begin!

The temptation to quit will be the greatest when you are about to succeed

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