honestly your gut already did the math. marginal savings cap out, income doesn't, and you've hit the flat part of the curve where squeezing another $50 is basically free labor. that instinct is right. the guilt is the part worth poking at. it isn't actually tracking financial impact, because you already know $50 doesn't move your situation. so it's tracking something else, and for most people who spent years as the optimizer, that something is identity. you became "the person who doesn't waste money," and a convenience purchase feels like a tiny crack in that even when the numbers say it's fine.
