Big goals significantly outperform small goals, medium-sized goals, and vague goals. It comes down to attention and persistence—which are two of the most important factors in determining performance. Big goals help focus attention, and they make us more persistent. The result is we’re much more effective when we work, and much more willing to get up and try again when we fail. "
