It doesn’t work. Your home is not a landfill. I understand that you don’t want to contribute to the growing landfills, but that doesn’t mean that you need to harbor garbage in your home. It’s OK to throw things away when they don’t work.
It no longer serves a useful purpose. If you don’t use it anymore, it could serve someone else much better. Sell it or donate it.
When you look at it, you feel crummy. If something has bad memories or associations, let it go! It doesn’t matter who gave it to you or how long you’ve had it. If you don’t love it, wouldn’t buy it in a shop, or it makes you unhappy when you see it, then it doesn’t need to be in your home.
It’s only taking up precious space. I understand that many of us have enough space to keep some things that we may need or do not exactly love, but those of us who have limited space need to be very careful that extraneous items don’t take the place of the items we do use and love.
You don’t want to clean it, dust it, pack it, move it, or insure it. If you don’t care enough to maintain it, you’ll enjoy the extra space much more once it’s gone!
