Sorry, it just means a shorter/summary version.
I don't think there is any complicated language in there. In fact it might have been that she used the word "short" not "abridged" but I was thinking of the word abridged, because that's the word that is used in publishing when they convert books to audio and skip long parts of it to make it easier to follow.
The How To Keep House While Drowning book is not really a plan, more of a mindset change. I think she does have some plans but it's not really a method in itself.
I think the plan with different rooms is The Organised Mum Method or TOMM? I don't get on with systems like that, but as I said before, anything that's worked for you before is worth trying again.
What I like about the A Slob Comes Clean method is that it differentiates between different kinds of cleaning. So you have the big cleans that you do when things have got a bit out of hand. And specific cleans of things like bathrooms. But then there are also daily tasks, which is doing the things that will block other tasks if they aren't done. I find this helpful because it means if I'm having a bad day, all I need to do is something/anything towards the dishes. So if I bring one cup through to the kitchen, then I'm good. This helps me to do at least one thing every day. Even on the lowest motivation day, I can move one cup (as long as I remember, which is sometimes the problem.)
I know that I definitely used to get very stuck because I had similar to what you describe - a kind of all or nothing mindset. So when I felt good and positive and motivated, then I'd be able to clean a whole section or a whole room. But then I'd be exhausted/worn out from that effort, and also I'd think "I just did that!" and not want to do it again, which means that not only would I not do any "big" cleaning, I wouldn't do the daily or maintenance cleaning either. This was a mistake, because within a day or two it would quickly revert to how it originally was.
Because of this, I also had this idea in my mind that "cleaning" = a whole lot of effort, energy, work, it takes a long time, it's unpleasant, it probably means dealing with icky stuff. The idea of having to do this EVERY DAY UNTIL THE END OF TIME is depressing and makes me want to hide in a pit of despair.
I didn't realise that maintenance cleaning, when the house is already fairly clean, is not like this at all. It's easy, it takes about five minutes, and if there is any left over food etc then it can just be easily thrown away rather than having to be chiselled off. Nothing is smelly and/or slimy because it hasn't started to rot.
