The Early (Not-So-Literary) Jobs Of 10 Great Authors

From a friend, Gilbert Tan, comes this link, The Early (Not-So-Literary) Jobs Of 10 Great Authors. I didn't know Kurt Vonnegut worked in public relations, that John Steinbeck was a tour guide, or that Joseph Heller was a blacksmith's apprentice. Heck, I didn't know any of the previous jobs of these authors, but it sure is interesting to know.
