I read this kind of books hoping to find useful ideas for my business. Here I can't find any.Even if one is just curious, the book is too full of platitudes. For instance, the Army chapter (in which I was genuinely interested) waxes high on gruelling experience, after-action review, and all that. But what's the big deal? Mutatis mutandis, I did the same in sports training twenty years ago.PS: I think I got unhelpful votes from people disliking my Army comments, so I edited this review to better reflect what I mean. But let me make it clear: independent of any view of the military, this is a bad book.
