Although either can be taken to an unhealthy extreme, most people fall on the side of having too much stuff and would benefit from having at least some of your gumption. Even America's poor often have more than one television in their place, and tons of clothes.
Don't you have books, though? I have four 7ft high bookcases filled to the max. (I go to library book sales and buy anything interesting for a buck) I like the idea of having more empty space (in a Frank Lloyd Wright way), but I don't know how I'm going to be able to part with these books. I bet if I went through them tonight, I'd may be able to get rid of 10% of them, at the most. It's sad.
