Meh. Not what I expected/wanted - it's more about "what are the activities that tend to provide more flow" / "what are the personality traits that tend to induce more flow", and it feels in the useless middle between "theory that would be interesting" and "practical advice" (so consequently, it's... theoretical advice, I guess). I also found the whole "flow is the One And Only Way To Get Happiness" stance annoying (and actually not necessarily what I wanted either), and somewhat judgemental at times.
