While there were nuggets of brilliant advice in this, and it helped me discover something about the business I'm running that will shape my life, I can't in good conscience give it more than three stars because there were whole chunks of chapters I didn't read, I just skipped over them. I mean, I get why they were there, as a way to explain why and how we react the way we do to different business situations, and if I was a different person, I might have really enjoyed it. But I'm just not that interested in psychology, and I feel that a summary would have been much more helpful than the pages and pages of references to studies and "What does that mean? Well what does that mean?" It was just a lot, and I ended up skipping a lot of it.
