Buffett's most favorite founder in Berkshire Hathaway, Rose Blumkin, is the ultimate example of grit: http://www.buffettsecrets.com/rose-blumkin-nebraska-furniture-mart.htm http://www.buffettsecrets.com/rose-blumkin-nebraska-furnitur... http://www.nytimes.com/1998/08/13/business/rose-blumkin-retail-queen-dies-at-104.html http://www.nytimes.com/1998/08/13/business/rose-blumkin-reta... Also a cool read is Dr. Arthur Jensen's research on calculating prodigies: http://stepanov.lk.net/mnemo/jensen.html http://stepanov.lk.net/mnemo/jensen.html. For me, the last paragraph is the kicker: "But the nature of this hypothesized advantage is really still uncertain. It might well turn out to be characterized more as a motivational variable than as primarily an attentional or ability variable. Why did Devi as a girl practice numbers so assiduously? Or why did the young Richard Wagner, to the consternation of his parents and teachers, repeatedly play truant from school just to be able to spend whole days concentrating on the orchestral scores of Beethoven's symphonies? Or Ted Williams, the famous baseball player, whose mother worried about the normality of his running all the way home from school every day to practice until nightfall relentlessly pitching baseballs through a hole in a backboard? It is the same story repeatedly in the biographies of the world's truly exceptional performers in every field. A good case could probably be made that the most exceptional performers and creative geniuses are much further out from the average of the general population on some kind of motivational factor than on any traits most psychometricians would consider a basic ability or cognitive capacity."
