I've been practicing this minimalist form of existence for some time now. For those that have too much stuff, here is how you get rid of stuff:

1. Mark a portion of your basement or apartment for some of your "stuff"

2. After a year or two if you have not had to use something at all from this pile get rid of it - ebay, craigslist, garage sale or donate.

3. You will feel good about less clutter.

4. Repeat till you're left with only stuff you really need.

The only place this hasn't worked for me is electronics "stuff".
