When we make any plan, we are guided by reasonable assumptions about what might happen in the future, using extrapolation from the known past. Morgan Gausel turns the process in the opposite direction, inviting us to see the many things that never change. He gives a master class on optimizing risks and seizing opportunities. Through a series of fascinating stories and insightful examples, he shows how we can use our new understanding of the unchanging to not squint at the uncertain landscape of the future, but to look back with our eyes wide open and focus on what is real. In this way, we can better anticipate change and achieve the greatest success, financial comfort and, most importantly, a life well-lived.
