In his most recent Bloomberg column, Liar's Poker author Michael Lewis answer's the letter of a young Wall Streeter who's pondering a move to Hollywood in the wake of the financial crisis.
Lewis tackles the difference between a job and 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. There’s no shame in either. Each has costs and benefits. ....
What Wall Street did so well, for so long, was to give people jobs that they could pass off to themselves as well as others as callings.
