Even the best decision doesn?t yield the best outcome every time. There?s always an element of luck that you can?t control, and there?s always information hidden from view. So the key to long-term success (and avoiding worrying yourself to death) is to think in bets: How sure am I? What are the possible ways things could turn out? What decision has the highest odds of success? Did I land in the unlucky 10% on the strategy that works 90% of the time? Or is my success attributable to dumb luck rather than great decision making? Annie Duke, a former World Series of Poker champion turned 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 dont 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.
