"An optimist is a person who starts a new diet on Thanksgiving Day"
About this Quote
The intent isn’t to dunk on hope; it’s to puncture the moral theater around restraint. Dieting, especially in mid-century American life where Kupcinet made his name as a columnist, isn’t just health talk. It’s status, virtue, and self-management packaged as a personal project. Thanksgiving exposes how porous that project is. You’re not battling only your appetite; you’re battling grandma’s insistence, the office party leftovers, the nostalgia of “tradition,” the way indulgence is framed as gratitude.
The subtext lands because the premise is technically plausible. Plenty of people do start “Monday” plans on impossible days, precisely because the declaration feels cleansing even if the follow-through doesn’t. Kupcinet’s joke captures that uniquely American kink: we love grand resets, we love excess, and we’d like credit for aspiring to one while participating in the other. Optimism becomes a punchline not because it’s naive, but because it’s performative.
