First, let's review Michael Lewis's distinction between a "career" and a "calling":
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.
I want both! I believe that you can create and obtain the things that you want.
