Wealth comes from systems rather than brute force. Ordinary people earn income by physical labor, trading time for pay; harder work does not guarantee greater gains, and they will eventually be limited by physical strength and age. The affluent build profit?generating systems: laying channels, integrating resources and constructing business models to keep manpower, capital and social connections operating in synergy. Isolated hard work delivers short?term, point?in?time returns. A mature wealth?building system brings cyclical, long?term gains. Systematic thinking is the core code for compound wealth growth.
