Michael Lewis on one's calling in life

[A job vs a calling:] The distinction is artificial but worth drawing. A job will never satisfy you all by itself, but it will afford you security and the chance to pursue an exciting and fulfilling life outside of your work. A calling is an activity you find so compelling that you wind up organizing your entire self around it -- often to the detriment of your life outside of it. 

-- Michael Lewis, in a Bloomberg Commentary about Wall Street

I have a strong feeling Posterous is my calling.
