You are mentally holding on to those things in the attic, whether you consciously realize it or not. It occupies passing thoughts, and when you want to do something, it becomes one of the chains in a long chain of shit-that-needs-to-get-done. "I can't go an visit my mother because she'll want to go swimming, my bathing suit is in the attic under all my old hockey gear, and if I have to move the gear, then I'm just going to donate it. Well, donating it requires a trip to the thrift store, which is closed today. I guess I won't visit my mother". (In software development, we call this process "yak shaving"). An item lying in an attic saps energy from you, often when you least expect it. So yeah, it can make you unhappy.
