What separates this from the tired "never give up" platitude is King's emphasis on *rightness* rather than mere persistence—she's not talking about grinding away indefinitely, but about the disciplined eye that knows when you've actually achieved something. A tennis player might hit a thousand serves, but the champion is the one who recognizes the exact moment the motion becomes efficient, the ball placement becomes purposeful, when luck transforms into mastery. You see this with devoted parents who revise their approach to a struggling child not out of stubbornness, but because they can distinguish between trying harder and trying smarter. King's insight cuts deeper than simple grit; it assumes you're intelligent enough to recognize excellence when you finally produce it.
