You have a schedule. You have things to do, places to go, people to see. You live by this schedule, and it runs your life; be it school, or work. Even being on vacation: you plan where to go, where to eat, what land marks you want to visit. Eventually it becomes all you know, all you'll do, for a very long time. Small things go unnoticed because they are too insignificant for your schedule. They are not the norm, they are not what you do.
