Learning to play an instrument is probably not something most people can get an 80⁄20 sort of benefit from, but it belongs in a class of activities in which some/many people can put minor effort in to reap the significant benefit of becoming a more interesting person, depending on one’s innate proclivities. Other examples may include dancing, singing, drawing/painting, certain sports/physical activities, craft-work, etc.
