Book excerpt: To survive and thrive in the fantasyland that is show business, you need to know the realities of writing and selling. J. Michael Straczynski learned these realities the hard way. With his help, you'll learn them the easy way. Here the writer/producer of Murder, She Wrote and creator of Babylon 5 tells you how it really is - and how you can really succeed writing scripts. Straczynski shows you the importance of distinguishing yourself, through professionalism and discipline, from the wannabes. He helps you strengthen your writing technique while urging you to bring your own vision to your work, avoid formula, and create from passion. And he takes you in for a close look at every entertainment medium hungry for good scriptwriters.
