Famous quotes containing the words constructive, set and/or theory:

    Work is a responsibility most adults assume, a burden at times, a complication, but also a challenge that, like children, requires enormous energy and that holds the potential for qualitative, as well as quantitative, rewards. Isn’t this the only constructive perspective for women who have no choice but to work? And isn’t it a more healthy attitude for women writhing with guilt because they choose to compound the challenges of motherhood with work they enjoy?
    Melinda M. Marshall (20th century)

    It’s the set of the sails and not the gales,
    That bids them where to go.
    Ella Wheeler Wilcox (1850–1919)

    The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.
    Charles Lamb (1775–1834)
