I have studied and studied this book and have read and reread (on my 22nd read of chapters 4 through 6, and everytime I pick it up again there will be something in there that pops out. I am serious about studying the material, this is not a book to be read, it is a book to be studied and studied intently. In fact, I am getting ready to buy a new one because I have already worn out the binding and the pages are getting ready to come out, I am still learning tons.
