Whatever your life’s work is, do it well. Even if it does not fall in the category of one of the so-called big professions, do it well. . . If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, like Shakespeare wrote poetry, like Beethoven composed music; sweep streets so well that all the host of Heaven and earth will have to pause and say, “Here lived a great street sweeper, who swept his job well."
-- Martin Luther King, Jr., “Facing the Challenge of a New Age” Montgomery, Alabama, 1956
