Famous quotes containing the word work:

    “I have everything in the world that is necessary to happiness, good faith, good friends and all the work I can possibly do. I think God’s greatest blessing to the human race was when He sent man forth into the world to earn his bread by the sweat of his face. I believe in toil, in the dignity of labor, but I also believe in adequate compensation for that toil.”
    —Anna Howard Shaw (1847–1919)
