Back in the day, before we had a surfeit of bright and shiny to hoard, people who collected were known as pack rats. My mom called my dad that. He didn't need anything (and was fond of saying everything we have, we own) but saw intrinsic value and needs in worthless things.
My sister was another story, being a classic hoarder, who could bury a room, making it unrecognizable as a human habitat. For some reason, I and my two other sisters went in a saner direction. Some families have more than one black sheep.
All the best,
