Making the decision to invest in the future at a time like this takes courage. Gulati defines courage as “a willingness to take bold, risky action to serve a purpose that you perceive to be worthy, usually in the face of an abiding fear.” That sounds daunting, especially if you believe—as Plato and Aristotle did—that bravery is an innate virtue. Gulati thinks the philosophers are wrong—and that courage is teachable. He argues that every one of us can cultivate the courage needed to lead through pandemonium and make the kinds of hard decisions that build stronger, healthier organizations—and he offers a playbook for doing so. Bravery, he writes, is a choice.
