Famous quotes containing the words comparison to other, comparison, staple and/or foods:

    “It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.”
    —Shusha Guppy (b. 1938)

    “[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
    —Sarah M. Grimke (1792–1873)

    “He draweth out the thread of his verbosity finer than the staple of his argument.”
    —William Shakespeare (1564–1616)

    “There are many of us who cannot but feel dismal about the future of various cultures. Often it is hard not to agree that we are becoming culinary nitwits, dependent upon fast foods and mass kitchens and megavitamins for our basically rotten nourishment.”
    —M.F.K. Fisher (1908–1992)
