Ecclesiastes 3:1 & 6 (KJV) To every thing there is a season, and a time to every purpose under the heaven: A time to get, and a time to lose.
It is defeat that turns bone to flint, and gristle to muscle, and makes men invincible, and formed those heroic natures that are now in ascendency in the world. Do not then be afraid of defeat. You are never so near to victory as when defeated in a good cause. --Henry Ward Beecher (1813-1887)
