I found the beginning to be quite interesting, but then it devolved into shallow recounts of various experiences that had to do with failure; I would have preferred an in depth analysis on black boxes. Maybe I could have gotten more out of it but I found it boring and just wanted to be done. It seems to fit into a category of business/psychology/self help books that take a cursory look at the literature to justify a fairly simple point, e.g. learn from failure and respond to failing positively.
