Doesn't work. Did that with my sister. I managed to clear out the dining room so that it wa possible to sit the family around the table to eat. Went back six months later and not only was that room uninhabitable but the amount of junk in other rooms had increased and the family was eating off trays in front of the television.

It's not the junk that is the problem, it's the way of thinking that leads someone to refuse to discard it. Or more likely there is some even deeper rooted cause that makes them think that way.

It can also be the case that the people they live with don't help either.
