Famous quotes containing the words work, potential and/or energy:
“Don’t you know there are 200 temperance women in this county who control 200 votes. Why does a woman work for temperance? Because she’s tired of liftin’ that besotted mate of hers off the floor every Saturday night and puttin’ him on the sofa so he won’t catch cold. Tonight we’re for temperance. Help yourself to them cloves and chew them, chew them hard. We’re goin’ to that festival tonight smelling like a hot mince pie.”
—Laurence Stallings (1894–1968)
