Not basses, but as somebody with a few hobby rooms / cupboards full of "stuff", I'll say this:
1) If it gives you pleasure - you're winning. (if it gives you more grief / stress / worry than pleasure - you're doing something wrong).
2) It's usually easier to acquire stuff than it is to, um, decquire stuff.
3) He who dies with the most toys - wins.
