Famous quotes containing the word sleep:
“I have had the accomplishment of something like this at heart ever since I was a boy.... So I feel tonight like the man who is lodging happily in the inn which lies half way along the journey and that in time, with a fresh impulse, we shall go the rest of the journey and sleep at the journey’s end like men with a quiet conscience.”
—Woodrow Wilson (1856–1924)
