Famous quotes containing the words colony and/or persistence:
““Tall tales” were told of the sociability of the Texans, one even going so far as to picture a member of the Austin colony forcing a stranger at the point of a gun to visit him.”
—Administration in the State of Texa, U.S. public relief program (1935-1943)
“Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and Determination alone are omnipotent. The slogan “Press On”, has solved and will always solve the problems of the human race.”
—Calvin Coolidge (1872–1933)
