The real sting here is Marie Curie's rejection of satisfaction—not as a moral failing, but as a cognitive blind spot. We're wired to feel relief when tasks finish, yet she's describing something more troubling: the human eye simply *cannot* rest on completed work the way it fixates on what's incomplete. A surgeon who has successfully performed a hundred operations will wake at night thinking only of the one technique she wants to refine; the scientist who published groundbreaking research immediately sees its gaps. This isn't ambition speaking—it's an observation about attention itself, about how accomplishment becomes invisible the moment it's finished, like yesterday's meal disappears while tomorrow's hunger announces itself loudly.
