In strict and competitive societies, success is not determined solely by ability or effort, but by their relationship to social expectations. This paper introduces a unified mathe- matical framework for the success index Q, emphasizing the role of self-expectation control (humility). We show that humility acts as a structural lowering mechanism of success thresh- olds. The theory is extended to generative AI usage, including free and paid models, where miscalibrated self-expectation can negate technological advantages.
