Don't be afraid to skim this book. Not every section will be applicable, but those that are make it worth the read.
The best thing about this book is it will get you thinking even if you disagree with what Mr. Ferris is writing. Yes, some of it is ethically questionable, but this is a book meant to challenge conventions. If you don't agree, dump that section, but keep going as there are sure to be some insights in it you will be glad you came across.
This book also suffers from the old adage, "If I'd had more time, I'd've written you a shorter letter." When I first read, "expanded and updated," I thought, "Cool! More for the money!" When I set it down for the dozenth time, I thought, "Ugh, just tell me what I need to know!" Because of the detail and the topic, much here feels already dated. Oh well, in the end I got through and am glad for it. I'm sure I'll be back to it as a reference tool, which would have been a better way to view the book than as a page-turner. But, then, that's probably just me.
