QUOTE : But in dozens and dozens of studies, Latham and Locke found that setting goals increased performance and productivity 11 to 25 percent.5 That’s quite a boost. If an eight-hour day is our baseline, that’s like getting two extra hours of work simply by building a mental frame (aka a goal) around the activity. But not every goal is the same. “We found that if you want the largest increase in motivation and productivity,” says Latham, “then big goals lead to the best outcomes. 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.
