Our former Kidney Foundation trucks are no more. I don't know why exactly. For a while, there were two and now none. I think they were sort of in competition with each other, oddly, and wondered if one drove the other "out of business". Personally, it had become less helpful to me. It is easier to have bags in my trunk and make my own decisions about when I would pull into a GWill than to have calls from them and need to have bags out at a certain time and day. I realized I was starting to dread their calls, because I wouldn't be prepared yet, or wouldn't be planning on being home that day, etc.
Have had a long conversation with dd19 on the phone, partially about decluttering. I've told her I think she needs to get graph paper and measure her room and closet here, and graph out the exact space she has here and plan how to use it better, see the truth about what she can keep and what she can't.
I'm still plugging along in my office area and in my sewing area. Hopeful.
Also threw out several pairs of old slacks. Not donation-worthy.
Best wishes to ddA with decisions, blessed. As far as one item a day, maybe you could make some requirements - like it either has to be "so" big, or "so" big a decision to let it go, etc. For instance, decluttering a dozen pencils might be the equivalent, in importance, of deciding to declutter a bracelet that used to be worn a lot, that sort of thing. I think each day you could decide how you felt about a decision - was it really enough or not.
I like Diane in Denmark's way of chatting and explaining, but do notice her house's level of clear space is remarkable. It may not be a reasonable level for other households. For her, one item may be a much greater percentage of available clutter than for most. (Being completely honest - blessed, for me, one item is not yet a drop in a bucket! not a droplet!)
