+1 on positive social interaction. Despite all of my FI efforts, I have almost always said, "yes" (when scheduling premits) to weekend get togethers with friends and family 2-4 hours away. Because we generally potluck when we get there, our only additional expense is gas, usually less than $40 in the family commuter, which is well worth it.
-1 on the "avoidance of unhappiness". To many people use this as an excuse for excessive convenience. For example: "I am tired of cooking so we are getting takeout". In this case, takeout will only provide a short burst of relief, not true happiness. A better term for permanently "buying" your way out of an 8-6 job is autonomy. Autonomy has been shown to make people truly happier over the long term vs the short buzz provided by the typical "avoidance of unhappiness". I would argue the pursuit of something that can make you truly happy (autonomy, quality social interaction) might be worth quite a bit of unhappiness to obtain.
