These captivating oral histories of the great Nobel Prize-winning physicist ostensibly have nothing to do with investing. In my view, however, the three qualities an investor needs above all others are independence, skepticism and emotional self-control. Reading Feynman’s recollections of his career of intellectual discovery, you’ll see how hard he worked at honing his skepticism and learning to think for himself. You’ll also be inspired to try emulating him in your own way.
