“If a man is called to be a street sweeper, he should sweep streets even as a 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 street sweeper who did his job well.”

“No work is insignificant. All labor that uplifts humanity has dignity and importance and should be undertaken with painstaking excellence.”

• Dr. Martin Luther King Jr.
