Famous quotes containing the words life and/or span:
“It is no small mischief to a boy, that many of the best years of his life should be devoted to the learning of what can never be of any real use to any human being. His mind is necessarily rendered frivolous and superficial by the long habit of attaching importance to words instead of things; to sound instead of sense.”
—William Cobbett (1762–1835)
“The last bear, shot drinking in the Dakotas
Loped under wires that span the mountain stream.”
—Hart Crane (1899–1932)
