A man sentenced to death obtained a reprieve by assuring the king he would teach his majesty's horse to fly within the year - on the condition that if he didn't succeed, he would be put to death at the end of the year. "Within a year," the man explained later, "the king may die, or I may die, or the horse may die. Furthermore, in a year, who knows? Maybe the horse will learn to fly." My philosophy is like that man's. I take the long-range view.
