Famous quotes containing the word work:

    A good story is one that isn’t demanding, that proceeds from A to B, and above all doesn’t remind us of the bad times, the cardboard patches we used to wear in our shoes, the failed farms, the way people you love just up and die. It tells us instead that hard work and perseverance can overcome all obstacles; it tells lie after lie, and the happy ending is the happiest lie of all.
    Kathleen Norris (b. 1947)
