Sure there are people with higher callings, geniuses like Einstein or Newton. But that’s not what we’re talking about here. We are talking about moderately intelligent people who will never contribute anything meaningful to humanity. For them work is not an excuse not to have friends or do “frivolous” things. Those frivolous things are what life are made of, so you better have a damn good reason if you avoid them. Being 10% of a team that is building some accounting software is not comparable to inventing calculus.
