At one point Gretchen Rubin says that Happier at Home is not a self-help book, but perhaps a "self-helpful" book. Do you think it qualifies as self-help? To me, it almost seemed more like an immersion journalism project, like A.J. Jacobs trying to follow everything in the Old Testament in The Year of Living Biblically. Although not much of it was helpful to me, it was often interesting to see the results.
