Well, the quote from Pearl S. Buck is way off. At least the author had the sense to quote Csikszentmihalyi. However, he admits he is not creative himself in many publications and interviews, so he does not have the perspective of the confident creator - a creator at the mature level of experience with the faculty.
Clearly their new book just doesn't get it all - and it can't because we don't know enough about it yet. But that won't stop fame starved writers grabbing for categorical headlines when they can't actually advance a meme that changes a domain.
My recommendation? Wait for my book and you'll see why Csikszentmihalyi's work is 20 years outdated and needs reframing with contemporary science, psychology, psychology and philosophy. Too bad the authors relied on it without full scope research.
