I am getting good at "Do I like this? Will I ever REALLY use it? How long has it been here (several years? --let it go)" And I am ruthless in getting rid of stuff. It goes to guild meetings, to garage sale, etc. But it goes OUT of my collection. I perform this ritual every year or so. Some of what I kept "last time" may well go out "this time". I love fabrics and have to get rid of some things if I am going to add new stuff.
