Seven to five; five to seven. This book has an elastic quality: I started out with an outline of seven chapters in May; I condensed it down to five chapters in July; now I am back to seven in September. As a result, some of what you have already read is now in future chapters, and new information is in chapters you may have already read. True to my spontaneous nature, I am revising the outline as I write the book. Sometimes the book leads, sometimes the outline does. It is difficult for me to be linear, so I have written pieces of every chapter before finishing the first one. Stay tuned, and please don’t get confused by my changes.
