If your living room is big enough, block of a 30 x 8 foot section. Mark it with tape on the floor. Set up a bed, dinette table, a television, a couch and a couple chairs. Get a small dresser for your clothes. And then try to live in that space ONLY for a week. You can cheat by using your kitchen for food and bathroom facilities. Consider the bathroom facilities as a campground shower house. Live in this space and see if that's big enough! Remember, you can only use the items you put inside that space. Everything else is off limits. One week, and see how you feel.
