A sudden interest in the simple things in life is driving you into a more spartan phase of living. Toss out old, unused, or worn-out items, and don't bother replacing them. Instead, learn to go without for a while. It will be a very educational experience. Once you go back to a more materialistic lifestyle (if you ever do), you'll truly understand the value of the things and people in your life. With just a little bit of imagination, small things can feel like very big luxuries.
