Getting rid of clutter is great, but it sucks if someone needed something you tossed out. Set up Unidentified Found Object (UFO) boxes around the house to collect random or unrelated items until you get a moment to organise them, or someone comes looking for them.
You can use small shoeboxes or plastic bins as UFO boxes. Place these boxes around the house so that whenever you find a random item, you can put it in a UFO box in the area you think might be the most appropriate. For example, if you find a cable, you can put it in your home office's UFO box.
Remember, these UFO boxes aren't a silver bullet. If you don't regularly empty and organise it, the random contents will simply pile up, and you'll need more boxes. Check these boxes regularly with your family, roommates or other residents of the house.
