For the revised edition

I want to thank Running Press and its publisher, Jon Anderson, for believing in this book enough to bring it out in this newly revised and updated format. This new edition is a result of the hard work of many people, especially my editor, Diana von Glahn, who showed me how to revise earlier material to make it fresh and relevant. Thanks also to Bill Jones and Alicia Freile of the Running Press design team.

Finally, a long overdue thank you to the original editors of the Addison Wesley edition in 1991, John Harris and Elizabeth Carduff. That this book continues to stay in print and find new readers and, now, even in a new incarnation, is a testament to their sensitive nurturing of a first time author. Thank you both for launching my writing career.
