I think the point is that most commute+cubicle work isn't usually work which is essential to survival. The call to be a little less cheerful is a call for everyone to see through the illusion that commute+cubicle is meaningful, essential work. We might find a greater contentment if we aren't filling what could be idle time with nonessential work.
