If you’re looking for a deeply moving opportunity for personal growth, I recommend letting your house get overrun by a plague of ladybugs. It worked for me.
It started in March, when, out of nowhere, hordes of the tiny, black-spotted red beetles showed up like so many miniature Volkswagens at a vintage car show. Within a few days the walls and ceilings looked like dot-to-dot pictures. Ladybugs crawled everywhere and clung to everything; it was nothing to find one perching on the end of the pen I was writing with.
