True, this book, at $6, is inexpensive. One day I thought, "If there is one good idea in that book, surely it is worth $6." That was a foolish thought. Not only are there no good ideas in this book (I'm convinced it was just written as a goof), but it wasted $6 that I could have spent at Taco Bell, not to mention the time I spent reading it.You have been warned.
