Please, do not read this book. While it has wonderful concepts it is horribly written and poorly produced. It is work to read. Not a fun read at all, and not worth the work considering there are a thousand other gurus out there that can tell you the same thing without the need to drone on and on and impose jargon on the reader. I would rather read a textbook cover to cover. If you read this book I promise that you will finish the first chapter and flip through it looking for good points. Other than the occasional flip through for core concepts, this is not a worthwhile book.
