There is a dullness in all forms of work, a “violence—to the spirit as well as to the body,” as Studs Terkel put it in Working. There are repeated tasks and empty time and moments you wish you were swimming. These are unavoidable, even in jobs we love and feel proud to have; these are natural, even if you’ve found your calling. It’s when those meaningless moments pile and mount, the meaningless moments that chew at your soul, that creep into the crevices of your brain and holler at you until ignoring them is not an option.
