Yeah, moving is a great way to motivate yourself to throw things out. A sure sign that you've got too much stuff is when you've still got boxes you haven't re-opened since the last time you moved, and that was in 1992.

>My old neighbor used to buy stuff for .50 - $1 at garage sales and then try and sell it on ebay for $10-20. This meant he had a lot of stuff. Anytime I wanted rid of it, I just carted it over their. When we moved he cleaned-up and I cleaned-out.
