Famous quotes containing the words operating, system and/or support:
“I love meetings with suits. I live for meetings with suits. I love them because I know they had a really boring week and I walk in there with my orange velvet leggings and drop popcorn in my cleavage and then fish it out and eat it. I like that. I know I’m entertaining them and I know that they know. Obviously, the best meetings are with suits that are intelligent, because then things are operating on a whole other level.”
—Madonna [Madonna Louise Ciccione] (b. 1959)
“The human body is not a thing or substance, given, but a continuous creation. The human body is an energy system ... which is never a complete structure; never static; is in perpetual inner self-construction and self-destruction; we destroy in order to make it new.”
—Norman O. Brown (b. 1913)
“An ordinary man will work every day for a year at shoveling dirt to support his body, or a family of bodies; but he is an extraordinary man who will work a whole day in a year for the support of his soul. Even the priests, men of God, so called, for the most part confess that they work for the support of the body.”
—Henry David Thoreau (1817–1862)
