Famous quotes containing the words control and/or chart:
““Have we any control over being born?,” my friend asked in despair. “No, the job is done for us while we’re sleeping, so to speak, and when we wake up everything is all set. We merely appear, like an ornate celebrity wheeled out in a wheelchair.” “I don’t remember,” my friend claimed. “No need to,” I said: “what need have us free-loaders for any special alertness? We’re done for.””
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
“Perhaps in His wisdom the Almighty is trying to show us that a leader may chart the way, may point out the road to lasting peace, but that many leaders and many peoples must do the building.”
—Eleanor Roosevelt (1884–1962)
