Query: Get it from the library BEFORE you spend your money...

As a public librarian, I see people come into the library all the time asking about books they've seen on infomercials. A good example of this is the Matthew Lesko books. Folks don't realize all the work they have to do to get the "free money," and borrowing the book from the library helps them realize the book is not all it's cracked up to be. It's the same with this book. Borrow it from the library first, because you don't have to spend money on it that way. Then, if you like the book, buy it if you choose. Some folks who have spoken to me about the book after reading it found it wasn't what they had expected.
