I also struggle with the clutter demon, although I'm pretty strict about keeping things past the point of needing-loving-using them. What I love to do is pass something on to someone who can need-love-use it after I'm done. One tool that helps me is Craig's List, the free section and the curb alert section. If I can't sell something for cheap, I just post it there and boom, it's gone, and often to young folks just starting out. It's a good feeling.
