Eh. I think the theory and reading/interpretation of Nietzsche (and Foucault, who is talked about nearly as much as Nietzsche) is pretty sound, but it gets kind of boring just nodding along in agreement the whole time. For anyone who has deeply read or studied these two already, little in here will come as new or a surprise.
The second half of the book leans more towards how to act within the world, yet it's spoken about in the most general vagaries ("live joyfully," "engage in projectuality," "projects that are joyful, effective, achievable") that are cool and inspiring when you first read Bonanno or Venomous Butterfly, but ultimately become sort of trite and dull over time. Perhaps I'm too much of a pessimist, but with literally zero concrete examples, I don't feel inspired (nor does it really leave much to argue against or poke holes in). It's also sort of unclear to me why the author consistently comes back around to fighting these big monsters while at the same time recognizing Foucaultian micro-powers as being just as (if not moreso) influential. It's probably worth mentioning as well that the focus on Foucault is his middle Power period rather than the more interesting care-of-the-self period.
