It would have been impossible to write this book without the advice and support of several dedicated individuals. In particular, my sincere gratitude goes out to Drs. Susan Carlson, Ashlyn Kuersten, Charles Crawford, and Douglas Davidson. This book would never have become a reality without their perseverance and sage advice during the early stages of the project.
My deep appreciation and many thanks go to Professors Marilyn McShane and Frank P. Williams III, series editors, for their valuable recommendations and support. I'd like to say a special thanks to Leo Balk, my publisher, for being so helpful, understanding, and patient throughout the entire process.
Lastly, I'd like to recognize the heroic efforts of all the individuals who contributed to this book in one way or another. I'm well aware that few people are privileged to work with individuals with such talent, vision, and good spirits.
