I recently read a book called, "The Hoarder in You" about the problems people have with accumulating too many things. Stuff.
There was one section where the author tried to differentiate between a collection and a stockpile! I think the point was that stockpiling is BAD whereas if you are a collector, it's GOOD.
I thought it was kind of funny, actually, since I figure I'm guilty on all counts! What about you???
