As I drove away from the Starbucks drive through window I was contemplating how in the world the employee that I just saw was so happy. If I had to get up on a Saturday morning and serve coffee to a bunch of people going out for the day while I was stuck at work I would not be so joyful. So as I thought about this I turned to my fresh brewed cup of joe and saw that there was a great little saying about the purpose of human life printed on the cup. Was the gal at the window so happy because she knew her purpose?
