This was a great audio book. I listened to it twice in one weekend while cleaning/organizing. I especially loved the part where they talked about the excuses you tell yourself to keep something around that you may not need. The little voice tells you "I might use it SOME day," and you counter that voice with "and who would be able to use it more than me?" Or, "It was so EXPENSIVE when I bought it," which you counter with "but that money was spent a LONG time ago, and now I can donate it and take a tax deduction for it!" "I could wear this if I just lost a little weight," the counter is "and if I lose weight, I can celebrate and buy new clothes." These logical responses really helped me get rid of clutter in my house. The part about internal/external motivation was helpful too.
