Bests & Worsts Reviews from Amazon

I really wanted to like this book. I tried. But I failed. This book is shallow and the only interesting "facts" introduced are, in fact, not facts. I happen to be a member of one of the small "flow-hacking" groups detailed in this book and, while he describes our facilities accurately enough, the claims he makes about language learning rates etc are entirely false. Don't read this. It's the book equivalent of a "peep" candy. Seems like it would be sweet, but then it dissolves without having given you an ounce of nutrition. This book was written in order to foster TED Talk invites, podcast interviews, and social media buzz. It's purely sensational and offers you, literally, nothing.
