Famous quotes containing the words negative and/or pressure:
“The negative always wins at last, but I like it none the better for that.”
—Mason Cooley (b. 1927)
“By school age, many boys experience pressure to reveal inner feelings as humiliating. They think their mothers are saying to them, “You must be hiding something shameful.” And shucking clams is a snap compared to prying secrets out of a boy who’s decided to “clam up.””
