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

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

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

The greatest mistake we make is living in constant fear that we will make one.

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

We learn more from failure than we do from success.

The journey of a thousand miles begins with one step. 

Failure is not the opposite of success, it is part of the success.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Success is not final and failure is not fatal. It is the courage to continue that counts.
