do you not feel your needs have changed Justin?
my current needs are fresh food and that I have to buy regularly anyway.
Apart from that, my house is as tidy as I am happy with - I hate mess, and I can't stand the idea of having to tidy up for visitors (even when we are unlikely to get surprise visitors these days)
We still have more books than we can read, games, wood in all shape (doors and part of furniture etc.) in one of the sheds... tools, most of the cardboard boxes from my last move properly stored away as they are always useful even to make things for kids.
There's no pile, no mess, no cluttered bookcase or drawers, I like my house. I can tell you where everything is when I need it too! I hate ornaments, I have pretty much none.
People do what they want in their own home, but the point is that KonMarie method is not to waste everything and having to buy everything again. Just get rid of crap.
