Famous quotes containing the words list of, list, service and/or companies:

    The advice of their elders to young men is very apt to be as unreal as a list of the hundred best books.
    Oliver Wendell Holmes, Jr. (1841–1935)

    I am opposed to writing about the private lives of living authors and psychoanalyzing them while they are alive. Criticism is getting all mixed up with a combination of the Junior F.B.I.- men, discards from Freud and Jung and a sort of Columnist peep- hole and missing laundry list school.... Every young English professor sees gold in them dirty sheets now. Imagine what they can do with the soiled sheets of four legal beds by the same writer and you can see why their tongues are slavering.
    Ernest Hemingway (1899–1961)

    You had to face your ends when young
    ‘Twas wine or women, or some curse
    But never made a poorer song
    That you might have a heavier purse,
    Nor gave loud service to a cause
    That you might have a troop of friends.
    William Butler Yeats (1865–1939)

    Socialite women meet socialite men and mate and breed socialite children so that we can fund small opera companies and ballet troupes because there is no government subsidy.
    Sugar Rautbord, U.S. socialite fund-raiser and self-described “trash” novelist. As quoted in The Great Divide, book 2, section 7, by Studs Terkel (1988)
