Famous quotes containing the word work:

    Work is an essential part of being alive. Your work is your identity. It tells you who you are. It’s gotten so abstract. People don’t work for the sake of working. They’re working for a car, a new house, or a vacation. It’s not the work itself that’s important to them. There’s such a joy in doing work well.
    Kay Stepkin, U.S. baker. As quoted in Working, book 8, by Studs Terkel (1973)
