Made some decluttering headway today;
the cartons of books were delivered,
sorting started right away, and I took three bags of books to the shop.

Even more momentous:
I made a reservation for next Wednesday
for 1-800-GOT-JUNK to come to my apartment building and
help me downsize by taking away the furniture that I can't fit
into my next apartment.
I was scared to call and make that reservation, but I did it.
That's less than a week away.
