Somewhere, a part of you believes that giving something away means losing it.
That belief has a name — loss aversion — and it's one of the most well-documented patterns in how people make decisions. We feel the pain of losing something more strongly than the pleasure of gaining something equivalent. Your brain isn't being irrational. It's running an old, very human bias, applied to a sweater you haven't worn in four years.
Closely related is what researchers call the endowment effect — the tendency to value things more highly once we own them. The moment something becomes "mine," a different part of the brain evaluates it. It becomes harder to assess its actual utility, harder to see it clearly, because ownership has added psychological weight that wasn't there before.

But notice what's actually being measured.
That bias evolved to protect scarce resources — food, shelter, safety. It wasn't built to evaluate a box of cables in your closet. The math it's running doesn't apply here, even though it feels like it does.
One of the most common fears underneath holding on is this: if I let go of this, I'll lose the memory it carries. But think of something you remember vividly from years ago — a moment, a person, a place. Do you have the physical object from that memory? In most cases, no. The memory persisted without the object. It always does. Objects can trigger memories, but they don't contain them. The memory lives in you.
What you release is rarely lost. It moves. To someone who needed it more than your closet did. The object's usefulness continues — it simply continues somewhere else.
You can release the thing and keep the meaning. They were never actually attached.
