How can one person possibly accumulate so much stuff?

I was just packing my closet and had a little meltdown...ok...I really just sat there muttering to myself...'it is ridiculous how much stuff I have'...over and over again.  Its crazy.  I purge stuff on a pretty regular basis, I've been selling a few things on ebay, and have already taken a carload to Goodwill.  And yet...still more stuff.

I admire those people who have pared down their possessions to 100 things.  I think I would need a professional organizer to help me get to that point because obviously I have a problem doing it on my own.

Ok enough of my whining...back to packing!
