Martin Luther King, Jr., on Vocation

In honor of Martin Luther King Day, I offer you something he said about vocation:

If a man is called to be a streetsweeper, he should sweep streets even as Michelangelo painted, or Beethoven composed music or Shakespeare wrote poetry. He should sweep streets so well that all the hosts of heaven and earth will pause to say, here lived a great streetsweeper who did his job well.
