Legendary business researcher Jim Collins reveals how extraordinary individuals like Grace Hopper and John Glenn unlocked their potential by discovering their unique encodings—innate capacities distinct from passion or talent. Collins shares transformational insights from his decade-long study showing that amazing lives unfold unpredictably, often peaking after age 50, and that finding your "happy hedgehog home" requires aligning encodings, economics, and inner fire rather than chasing a predetermined plan. Encodings are durable, innate capacities that emerge through life experiences and differ fundamentally from passion or talent; aligning work with your encodings, not just what you love, creates sustained fulfillment.
