Still the master of happy

I just finished a (nother) book-by-book tour of Aristotle's Nicomachean Ethics aided by the video lecture commentary of Father Koterski and his lovely Teaching Company course (here). I am a big fan of the positive psychology movement (here) and its emphasis on human happiness, and indeed applying the methods of social science to human happiness is a recent phenomenon; however, the conclusions of the movement are largely Aristotle's, so why not read it from the source?
