I collect. And then I sell them. I don't have it in my budget to accumulate much of a collection at once... so I never have a big collection. It is constantly being sold/traded for other items. Than way I lose less money, and spend a few precious months becoming familiar with a piece, and I am never cluttered. The few weaponry/tools that I keep are onces that I actually use.
Maybe if I had a lot more money and a very settle lifestyle, things would change?
I don't know, but I doubt it.
