In a book by Paul Boller, the author tells a story about Woodrow Wilson. One of his cabinet members praised him for his short speeches. He then asked Wilson how long it took him to write a speech. "It depends," said Wilson, "If I am to speak ten minutes I need a week for preparation, if fifteen minutes, three days; if half an hour, two days; if an hour, I am ready now."
