Famous quotes containing the word direct:
“Pleasure is the rock which most young people split upon; they launch out with crowded sails in quest of it, but without a compass to direct their course, or reason sufficient to steer the vessel; for want of which, pain and shame, instead of pleasure, are the returns of their voyage.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
