Hell to the yeah I do this. I've never been a hoarder, but I've always bad about getting rid of something that might have value. "Oh, I could fix this and it would be perfectly fine" or "Oh, I might have use for this some day." Those things are true, but the reality is 1) If I needed it, I already would have fixed it, and 2) if I have need for XYZ someday, I can worry about it then.
I've come around to the reality is that if you have crap you don't need it is like a millstone around your neck, it has negative value, it is a burden. Sell it to the lowest bidder and get rid of it.
