I remember one of my teachers at one point in my schooling mentioning that there is a balance between the good days and the bad days you’ll get. The exact phrasing used to express this idea was “Some days you get the elevator, some days you get the shaft.” Morbid, perhaps, but it’s a saying that has stuck with me since then. I really like similarly structured euphemisms and turns of phrase, and I just learned the name for them: isocolon.
