A Big Box Of Nothing

Are you anything like me? As I clean the house I put things that don't go in a room in a box and then move that box into another room and keep adding to it. Then we sit and take the items in the box and put them away. I'm usually left with a ton of items in the box that I don't know what to do with. CAT5e cables, different craft items, kids things...but I don't have a specific place for them. So they sit, until the next time I clean and the box gets added to. By the time we moved to this house the box was full of stuff. Some items I had been looking for, others just junk. I'm wondering if something doesn't have a space...should I just throw it out?
