My husband and I both collect a lot. But I also see the difference between the things we collect and display and enjoy and the stuff that just gets stuck away and kept because no one wants to clean out. I just cleaned my junk room out last winter. I bought shelves to keep stuff on and found a lot of stuff I just didn't want anymore and tossed out.
I have a ton of antiques (furnture, dishes, collectibles and vintage signs). I"m the only one that likes a lot of it but that's okay because it brings me joy to drink my coffee or tea out of a vintage cup or eat off 100 year old dishes. That's worth having the things around to me.
