Good for you, Helen. By next New Year's Day, you can look back with satisfaction. Congratulations.
The only resolution I made is an ongoing one. I'm in the process of moving- and my resolution is to pare back, to simplify, to minimalize. So I've given away and donated loads of stuff. Yesterday, as an example, I called the local homeless shelter and gave them THREE sleeping bags (What do I need with THREE? I don't even need ONE anymore.) and a good dufflebag stuffed with tote bags. When I find my tent, that's going too.
When I set up housekeeping again a couple of months from now, I'm going to be very pleased with myself. But I'll have to be careful- I've done this before- and still have always ended up accumulating HUNDREDS of books. They are the one thing I just cannot resist. But maybe I'll accept that failing and just plan to periodically donate a boxful of them to Friends of the Library. I've gotten rid of my BIG bookcase and kept only the small ones that are almost filled with the books I couldn't bear to part with.
