This book will put you to sleep, its really just a bunch of stuff your already aware of, you don't need the book, read it yourself. If something in this book changes how people think about certain things then thats one thing and I may buy it. Otherwise Im not interested at all with this..it only encourages negativity on my part. :(
Bad review
