The Passion Paradox

I'm disappointed in this book because I enjoyed Peak Performance, and was able to take away useful tidbits of information that I semi-successfully integrated into my life. I was hoping this book would focus mostly on sports examples but it ended up being more like any other generic self-help book I've read (and in fact, referenced quite a few of those). And like many of those books, pretty much everything you need to know is in the title/subtitle. So I can't say I found anything particularly novel or insightful here. Maybe a sign I should stop reading these?
