What Motivational Quote(s) keep you going?

[Brian Feltz]

Im sure, like me, you have quotes posted around your work area or in your notepad. What are they? I have several:

"Someday is Today"
"You are your own limitations, you are your own success"
"Whether you think you can, or you think you can not, you are right" -Henry Ford
"I can't understand why people are frightened of new ideas, Im frightened of the old ones" -John Cage

Also, have you seen Arnold Schwartzneggers 6 rules to success youtube video? That pumps motivation into my viens every time!
