If you haven't quite figured out how to liberate yourself from the indignities of your chosen or unchosen calling, the answer is at hand. Start a guava-flavored-doughnut shop! Or satisfy your long-cherished wanderlust as the proprietor of a traveling popcorn wagon. Or conduct natural-childbirth classes, or organize a dog-walking service, or join the ranks of those carefree plutocrats--the freelance photographers of the world. You may be set back a bit by the preparation and research (estimating the custom-painted-T-shirt market, finding out whether there's already another survival school on your block), but in the meanwhile you can abandon yourself to 18 chapters of not-quite-fantasies, some accompanied by surprisingly practical suggestions and bibliography.
