Declutter is one of the activities required of me now.
For four years I have put off decluttering my apartment (2Bd, 1Ba). Now I'm getting started. There is a lot of trash in the form of papers and old files, so that is getting removed a little at a time. The unneeded clothing is going to places like St Vincent de Paul, Goodwill, or whatever drop-in box is convenient (other organizations).
The unneeded books are going to a place called More Than Words. It combines the sorting and selling of second-hand books with a mission for assisting disadvantaged high-school students. I love driving a back-seat-load of boxes of books to More Than Words. The students there are always ready to help unload the boxes and to carry the books away to their own storage room.
The apartment still looks cluttered at the moment, but I know what has been cleared out and I can see the clear spaces that used to have piles or boxes stacked in them. Eventually, though, I will have to clear out the file cabinets that have files I have not looked at, or needed, in years. For now the cabinets can sit there while I get rid of the stuff outside of the cabinets. I'll probably get rid of the cabinets themselves anyway, when the time comes.
Most likely I will have to downsize to a smaller space and so eventually some of the furniture will have to go as well. Then there is what is left of a cheap bookcase. The bookshelves were made of particle board. I loaded the shelves up with books, and one day they came apart and the books spilled all over the wall-to-wall carpet. Now the pieces of the shelves are waiting for me to get someone to remove them as "junk".
