Some people need structure and the society provides that in one way by suggesting everybody making a schedule and sticking to it. Those who are successful at it, thrive and might think they love being a JW.
Then there are those whose lives spill out over the edges of a schedule (you can call it dysfunction or maybe they are just bohemian types at heart) and end up becoming unhappy. The bohemian types are unhappy because they don't have time to express themselves, maybe thru writing or art, or something like that.
