“A writer need not devour a whole sheep in order to know what mutton tastes like, but he must at least eat a chop. Unless he gets his facts right, his imagination will lead him into all kinds of nonsense, and the facts he is most likely to get right are the facts of his own experience.” — W. Somerset Maugham
