The floors in this old place of ours are anything but level. In 160+ years since it was built, stuff has settled. All it takes to deal with this is a quick check with the level, and a shim or two to set things to rights.

I mention this because I have been on a tear since late last week. I am fed up with the clutter and crap that has accumulated in our living room, and I am determined to do something about it. I have rearranged some furniture, sorted through piles and boxes, and have already made two trips to the charity store. Lots more is still left to do, but I can see progress ... and progress fuels motivation. We will see how long this spell lasts.
