When your schedule loosens up and presents you with a great big chunk of free time today, fill up that unexpected gap with intellectual pursuits. Pick up a thick novel, see a foreign film, or do whatever else that gets your mind really humming. This is a good time for deep thought and contemplation: it would be a shame to fritter away the hours with mindless channel-surfing, shopping or napping. You need to do something mental, something stimulating.
