Sit alone in a room and let your thoughts go wherever they will. Do this for one minute. . . . Work up to ten minutes a day of this mindless mental wandering. Then start paying attention to your thoughts to see if a word or goal materializes. If it doesn’t, extend the exercise to eleven minutes, then twelve, then thirteen . . . until you find the length of time you need to ensure that something interesting will come to mind. The Gaelic phrase for this state of mind is “quietness without loneliness.”
