Great Idea for a book. I was anticipating its release with excitement. After completing it last week, I have to say that the opportunity was wasted.
He does what he says, but gets about an inch deep with the individuals, then he crams the few insights they had into whatever his outline's mantra is for that chapter (he puts words in their mouth to fit his format).
Also, the author is confused about what kind of writer he is. I mean, this book isn't Old Man and the Sea, so it seems out of place when he slips in and out of wild descriptive periods and clever similes that seem like he's been waiting to use them. They feel shoe-horned into descriptions.
But I don't want to just bash him here. Its an interesting read, but seems shallow for all the time he put in. He is also genuine about his interest in the subject.
