Ten years ago when i moved out of my parents' house, I had a rusty old car and little else. I had no possessions to speak of. I didn't even have a TV. I just had a few clothes and that was it. Since then I have gotten married, had kids and bought a house. It would easily take two semi trailers to move me now. And I'm not kidding either!
We have a good sized home with lots of storage areas, which are mostly full. We have tons of stuff. Too much? (is 6 TV's too much?) Probably but what do i care. I have a great family and if it makes them happy it makes me happy. Personally I don't require much.
