The book I read was actually called: "Messie No More: Practical Steps to Put the Messy Lifestyle Behind You"... but it's probably the same book.
We have come a long way in our understanding of how ADHD affects women and of the actual facts of this neurodivergence.
If you can glide over the obvious inaccuracies (thoughts on ADHD, circa 1989), the occasional "olde world" humor, and the repetitive invocation of Biblical quotes and exhortations of how God can help you through this (unless He shows up at my house, ready to help, he's not my guy here), there are some interesting tools in this toolbox.
Not the most sophisticated, but like all tools, it depends on whether they are useful for what you need to do, and whether they work for you.
Honestly, I love her approach that going a full-180 and suddenly maintaining one of those "museum" homes is really not much healthier, and that an average-but-improved household goal is best.
She is very supportive of women who suffer and does focus on the self-esteem issues and the fraught-with-trial-and-failure cycle, so I am pleased that I picked it up.
But definitely dated - can't really hold that against it too much - and I couldn't use the "starts with God" parts. Fine if that works for you, but that's not my happy place.
