If you have some kind of attachment to something, then you shouldn't throw it away. It has real value to you. The kind of stuff you should toss is the stuff that you're keeping because you think it's valuable in the abstract.
Indeed. I have a box in my basement with an incomplete set of work for school since grade school and other junk. Each individual piece is pretty useless, and has low sentimental value. The box is easy to store.
