I've been away from these threads for some time, and still not exactly finished, but have been easily keeping the 'done' bits tidy.
Also, to say how remarkably altered my mindset is. Because I've sorted everything out, I feel like I 'know' the house and its contents so much better. This has had the knock-on effect of making me want to keep things tidy, and kind of cherish the house I suppose, and so whipping out the hoover or wiping down a surface is something I (mostly) want to do, rather than feeling like a tedious chore to be put off, and off, and off (until we got visitors!).
And, as previous posters have said, getting rid of all the crap makes it a hell of a lot quicker to do a bit of cleaning.
My house is still nowhere near as neat as the pics posted by prettymess, but just in a different league to this time last year.
The other pleasing side effect was, when we got a rescue puppy just after Easter, puppy-proofing the house was reasonably straightforward. And having her has definitely forced us to the next level of kondo, as everybody in the house has to keep their stuff out of reach if they don't want it chewed to destruction. And, often, that means people put stuff away!
