From the subtitle, "mistakes I made so you don't have to," I was expecting a lot more in the way of practical anecdotes. There's some of that, but not what I was expecting. That's fine, it's just a different book than I originally thought. A lot of very good advice, though somewhat generic. The book's general theses are: work hard, progress is slow, it's never too late, and please stop scaring your horse. These are all good theses.
