'...if it falls to your lot to be a street sweeper, go on out and sweep streets like Michelangelo painted pictures; sweep streets like Handel and Beethoven composed music; sweep streets like Shakespeare wrote poetry; 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., 'The Three Dimensions of a Complete Life' in Letter from a Birmingham Jail, p.36.
