In my Catholic grade school, this was a popular saying for the nuns who were my teachers:
But I prefer this take on idleness:
“Idleness is not just a vacation, an indulgence or a vice; it is as indispensable to the brain as vitamin D is to the body, and deprived of it we suffer a mental affliction as disfiguring as rickets. The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole, for making unexpected connections and waiting for the wild summer lightning strikes of inspiration — it is, paradoxically, necessary to getting any work done.”Tim Kreider in his New York Times essay “The Busy Trap” from 2012
If you need me this weekend, I’ll be kayaking. Or biking. Or walking. Or just standing (or sitting) idly by.
