I just went through a major purge in order to downsize from a 1000 sq ft house, to a ~220 sq ft RV. I've still got too much stuff, but I'm getting closer.<p>Stuff weighs you down, and makes making major life changes more difficult (even if you know you need them). I stayed in Mountain View at least a year longer than I should have, from a contentment perspective, mostly because the thought of moving was just too much to handle.<p>Some things I will never allow myself to again have a lot of: Books, CDs and DVDs, more furniture than I use every day, more rooms than I use every day, more computers than I use every day, and <i>anything</i> (clothes, tools, foodstuffs, kitchenwares, etc.) that can sit in a closet or on a shelf for more than a year without being needed. Even now, I think I have probably twice as much stuff as I really need, and I'm planning to move into a smaller, but nicer, RV in a few months, once I've downsized more thoroughly.
