“In an age of instrumentalization, the hobbyist is a subversive: he insists that some things are worth doing for themselves alone, despite offering no payoffs in terms of productivity or profit. The derision we heap upon the avid stamp collector or train spotter might really be a kind of defense mechanism, to spare us from confronting the possibility that they’re truly happy in a way that the rest of us—pursuing our telic lives, ceaselessly in search of future fulfillment—are not. This also helps explain why it’s far less embarrassing (indeed, positively fashionable) to have a “side hustle,” a hobby-like activity explicitly pursued with profit in mind.”
