Famous quotes containing the word design:

    Delay always breeds danger; and to protract a great design is often to ruin it.
    Miguel De Cervantes (1547–1616)

    The reason American cars don’t sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. That’s why the American auto industry is in trouble: no design, no desire.
    Karl Lagerfeld (b. 1938)

    To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.
    Marilyn French (20th century)
