The cost of owning something includes the space it prevents you from using differently.

Price is only the part of ownership you pay once. Everything you keep also takes up a shelf, a corner, a share of the room, and that space could have held something else. A cupboard full of things you might use one day is a cupboard you cannot use today. The real cost keeps arriving quietly, in the form of options you no longer have.

Pick one crowded surface or cupboard this week and ask what the room would do if it were empty. If that answer appeals more than the contents, it is useful information. Let a few things go and see whether you miss them.
