Famous quotes containing the word hard:

    It is what we imagine knowledge to be:
    dark, salt, clear, moving, utterly free,
    drawn from the cold hard mouth
    of the world, derived from the rocky breasts
    forever, flowing and drawn, and since
    our knowledge is historical, flowing, and flown.
    Elizabeth Bishop (1911–1979)

    Her fortune, too, lies there,
    Converted into cool hard steel
    And right red velvet lining;
    While over her tan impassivity
    Shot silk is shining.
    Gwendolyn Brooks (b. 1917)

    One of the main things that interfere with our joy is the belief that if we try hard enough, read the right books, follow the right advice, and buy the right things, we could be perfect parents. If we are good enough as parents, our children will be perfect too.... Unfortunately, what comes from trying to live out this philosophy is not perfect children but worried parents.
    Lawrence Kutner (20th century)
