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.”
