get rid of all my clutter

Its amazing how much crap you can aquire. My wife and I have moved several times and She has these heavy boxes marked fiances. I have brought these heavy boxes up and down to the attic at every move. The last time I broke one of the steps on the ladder. I decided to open the boxes and put the contents into smaller boxes to lighten the load. What I found was receipts, statements and check stubs from 1975. It was 2004 when I found this and told her I think its safe to shred these. Its even harder to eliminate clutter when your spouse is a pack rat too.
