Martin Luther King Jr. on Vocation

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