I have been at this some years now. There was a cognitive breakthrough when I realised that I didn't have to get the place perfect first time and I started thinking in terms of "drafts", as in writing a novel.
Well, I'd say I'm coming to the end of the second draft. The biggest job (the new bathroom) was completed last year, G rearranged his study the other week, so apart from having some double-glazing installed the rest is just going to be superficial tidying, cleaning and keeping up with the redecoration.
In order to make the spare room ready for our son and his wife to stay the other weekend, I moved all the stray clutter into my study (mostly files, folders and papers) -- which means that all the rest of the house is now reasonably tidy and I have one very small, very messy room to sort out.
So, as long as I can keep routine tidying and cleaning going in the rest of the house the end of the second draft is in sight!
Just don't mention the garage or the garden. Those are my next big projects and will take some time...
