The Gettysburg Address was written in a few hours and took but a few minutes to read. The other public official who spoke on that occasion went on for two hours and nobody remembers who he was or what he said. Some of the clearest utterances are composed in a great hurry under a strict deadline. When people work on something for too long they can lose focus, become wordy, and end up with a pile of mush. That's why I practice writing aphorisms. If you can't make your point in one paragraph, then maybe you have no point to make.
