In an adaptation from his new book, Dacher Keltner explains the secret to gaining and keeping power: focus on the good of others.
Whereas the Machiavellian approach to power assumes that individuals grab it through coercive force, strategic deception, and the undermining of others, the science finds that power is not grabbed but is given to individuals by groups.
What this means is that your ability to make a difference in the world—your power, as I define it—is shaped by what other people think of you. Your capacity to alter the state of others depends on their trust in you. Your ability to empower others depends on their willingness to be influenced by you. Your power is constructed in the judgments and actions of others. When they grant you power, they increase your ability to make their lives better—or worse.
