Wow... I didn't think anyone could say the same thing so many different ways and so many different times and sell their book. The only reason this book sells is because their are good salesman who convene department head to use this book.I read the text book cover to cover and after writting my notes out from the whole book, my notes were only four pages long, this book is a waste of time.I will admit their are several quotes and passages that made me chuckle but, over all this is not a good buy.I am selling my book back and I'm only half way through my semester.
