Historically, leisure was the time to “do what you will,” the eight hours of the day not spent on working or resting. People cultivated hobbies, anything from walking aimlessly to constructing model airplanes. What mattered is that it wasn’t done to make yourself a more desirable match, to declare your societal status, or make some extra money on the side. It was done for pleasure. Which is again why it’s so ironic that millennials, stereotyped as the most self-obsessed generation, have lost sight of what doing something simply for personal pleasure looks like.
