“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.
