““I have been enormously impressed by the role that pure chance plays in determining our life history. I was reminded of some famous lines of Robert Frost: Two roads diverged in a yellow wood, And sorry I could not travel both I took the one less travled by, And that has made all the difference. As I recalled my own experience and development, I was impressed by the series of lucky accidents that determined the road I traveled. > From "Lives of the Laureates" pg.67””
