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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

I can is 100 times more important than IQ.

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

Tough times never last, but tough people do.

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

I have not failed, I've just found 10,000 ways that won't work.

Time is your friend, impulse is your enemy.

Never underestimate the importance of small steps. small steps = big changes. 

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

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

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