Annie Duke, a former World Series of Poker champion turned business consultant, draws on examples from business, sports, politics, and (of course) poker to share tools anyone can use to embrace uncertainty and make better decisions. For most people, it's difficult to say "I'm not sure" in a world that values and, even, rewards the appearance of certainty. But professional poker players are comfortable with the fact that great decisions don't always lead to great outcomes and bad decisions don't always lead to bad outcomes.

By shifting your thinking from a need for certainty to a goal of accurately assessing what you know and what you don't, you'll be less vulnerable to reactive emotions, knee-jerk biases, and destructive habits in your decision making. You'll become more confident, calm, compassionate and successful in the long run.

Iconic couples’ therapist and bestselling author of Mating in Captivity Esther Perel returns with a provocative look at relationships through the lens of infidelity.

An affair: it can rob a couple of their relationship, their happiness, their very identity. And yet, this extremely common human experience is so poorly understood. What are we to make of this time-honored taboo—universally forbidden yet universally practiced? Why do people cheat—even those in happy marriages? Why does an affair hurt so much? When we say infidelity, what exactly do we mean? Do our romantic expectations of marriage set us up for betrayal? Is there such a thing as an affair-proof marriage? Is it possible to love more than one person at once? Can an affair ever help a marriage? Perel weaves real-life case stories with incisive psychological and cultural analysis in this fast-paced and compelling book.
