I've been working for 5 1/2 hours, and the apartment STILL looks like shit!
It has to get worse, before it gets better.
Focus on what has gotten better, even if it is not obvious yet.
My bedroom looks absolutely awful right now. Still working on the books. Have been dusting a lot of them outside the window today, and a few shelves look neat, clean and well filled. For the rest, piles of dusty books everywhere. And the scent of both dust, and cleanliness. Weird mixture. Wonder how much I will be sneezing tomorrow-morning.
