What separates Napoleon's observation from mere cheerleading is his focus on *vocabulary itself*—he's saying that the truly capable person has already removed a word from their working language, the way one might strike an outdated reference from a manuscript. The word "impossible" doesn't disappear because you're optimistic; it vanishes because you've trained yourself to think in terms of constraints, timing, resources, and alternatives instead. A surgeon facing a malformed blood vessel doesn't declare it impossible to repair; she asks what's technically possible given her tools and the patient's anatomy, then builds her approach from there. The fool, by contrast, reaches for "impossible" as conversation-ender, a way to stop thinking rather than start solving.
