One of my first jobs was at a not-for-profit think tank.  I figured out pretty damn quick that I needed profit to live in New York City.  I also noticed that at 23 I was too easily distract–oooh, something shiny!–ed to do much of the thinking thing.  So, wisely, I went to work in publishing.  I mean, I read walking down the street, surely I would really focus if it was my job.
