Have you ever wondered what it's like to be a celebrity?James Fixx, author of ''The Complete Book of Running,'' a best seller, relates some fascinating insights into ''success'' in his newest book.
He shows that fame ''is never a solitary phenomenon. It's a contractual relationship, one that requires not just an actor but a willing audience as well.'' He didn't dream of the success that would come his way as an author, only of the joy of devoting his time to writing about his sport. His new book probes deeply such questions as: Is fame something you work toward, or the result of your work? How long does fame last?
