Famous quotes containing the words world, organization, sea, state and/or code:

    For a parent, it’s hard to recognize the significance of your work when you’re immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, “I’m making my contribution to the future of the planet.” But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.
    Joyce Maynard (20th century)

    To fight oppression, and to work as best we can for a sane organization of society, we do not have to abandon the state of mind of freedom. If we do that we are letting the same thuggery in by the back door that we are fighting off in front of the house.
    John Dos Passos (1896–1970)

    Times go by turns, and chances change by course,
    From foul to fair, from better hap to worse.

    The sea of Fortune doth not ever flow,
    She draws her favours to the lowest ebb;
    Her tides have equal times to come and go,
    Her loom doth weave the fine and Coarsest web;
    Robert Southwell (1561?–1595)

    A state always calls itself fatherland when it is ready for murder.
    Friedrich Dürrenmatt (1921–1990)

    Many people will say to working mothers, in effect, “I don’t think you can have it all.” The phrase for “have it all” is code for “have your cake and eat it too.” What these people really mean is that achievement in the workplace has always come at a price—usually a significant personal price; conversely, women who stayed home with their children were seen as having sacrificed a great deal of their own ambition for their families.
    Anne C. Weisberg (20th century)
