Compliments make me vain: & when I am vain, I am insolent & overbearing. It is a pity, too, because I love compliments. I love them even when they are not so. My child, I can live on a good compliment two weeks with nothing else to eat.

Mark Twain (1835-1910) American writer [pseud. of Samuel Clemens]

Letter to Gertrude Natkin (1906-03-02)

In a similar vein, his biographer, Albert Bigelow Paine, in Mark Twain: A Biography, Vol. 4, ch. 250 (1912), recalled Clemens saying: "I can live for two months on a good compliment."
