I wish I had better advice for you. My husband is such a pack-rat that he still has a sucker that his 1st grade teacher gave to him over 30 years ago. That rediculous sucker is older than I am! I don't think he even knows where it is right now, but even mention the idea of throwing it out, and he goes nuts.
He had probably the worst looking home office you've ever seen. It hadn't been vaccuumed in 5 years, because we couldn't get to the carpet to vaccuum it. We put the house on the market. 6 months later, I was still hounding him to clean out his office. House still hasn't sold. I ended up taking the first panic attack of my life (and I'm *always* the stable one, who takes *everything* in stride, and keeps everyone else from falling appart). All off a sudden, we have a beautiful clean home office. The desk has been shrunk by two thirds, five computers have disapeared, all the clutter is gone. We found the carpet, and were pleasantly suprised at how good a shape it's in. However, the panic attack was not fun, and I wouldn't recomend it.
ETA: the rest of the house was always tidy, and the office was gated off, so the kids had no access to it.
