Not quite. In my view, Prof. C's work is more fundamental in nature; he doesn't
prescribe anything particular. But describes what works, based on his observations, and lets us judge for ourselves.
Among other things, he goes in detail (with studies backing up his points) on what provides "optimal experience" to humans. And covers topics like "order in consciousness", "sense of self", "entropy", "freedom", "purpose", and so on.
A couple of random quotes from my notes:
(1) "The inevitable consequence of equally attractive choices is uncertainty of purpose; uncertainty, in turn, saps resolution, and lack of resolve ends up devaluing choice. Therefore fredom does not necessarily help develop meaning in life—on the contrary."
(2) "There is one very important and at first apparently paradoxical relationship between losing the sense of self in a flow experience, and having it emerge stronger afterward. It almost seems that occasionally giving up self-consciousness is necessary for building a strong self-concept. Why this should be so is fairly clear. In flow a person is challenged to do her best, and must constantly improve her skills. At the time, she doesn’t have the opportunity to reflect on what this means in terms of the self—if she did allow herself to become self-conscious, the experience could not have been very deep. But afterward, when the activity is over and self-consciousness has a chance to resume, the self that the person reflects upon is not the same self that existed before the flow experience: it is now enriched by new skills and fresh achievements."
