Robert Rubin, former secretary of the Treasury and co-chairman of Goldman Sachs, shares thoughts on decision-making developed over more than six decades in markets, business, government, and politics, and offers readers an astute and original guide for navigating uncertain times In 1958, as a college sophomore, Robert Rubin took a class that changed his life. The class was introduction to philosophy, and the professor, Raphael Demos, instilled in his students an idea that was simple yet profound- There is no such thing as certainty. For Rubin, this led to a critically important question- How can we make sound decisions in a fundamentally uncertain world While serving in some of the most significant roles in markets, business, and government, Rubin has grappled with that question. Time and again, when faced with a high-stakes decision, he turned to his most trusted tool-a simple yellow legal pad. Rubin's yellow pad or more recently, his iPad became an expression of a larger decision-making philosophy that has both lasted and shaped a lifetime. In The Yellow Pad, Rubin lays out that philosophy with depth and detail, and presents a compelling intellectual framework for confronting some of the most difficult issues we face today. The Yellow Pad contains a former Treasury secretary's approach to economic policymaking. A former Goldman Sachs senior partner's approach to personal investing and understanding.
