There are lots of sites reposting the same information about what habit-training is, why you should do it, and how to (and the suggestions for how to are very similar and general: 1)Focus on one habit at a time, 2)Focus on it for 6 to 8 weeks, 3)Introduce it, talk about it, explicitly teach it, 4)Correct your child when they exhibit the bad habit every time it happens, and praise your child when they exhibit the good habit.)
The sites say you should begin with obedience, truthfulness, and attention. I agree that obedience is the most important.
There are the habits Mason writes about in her series, but she doesn't give a tidy list with bullet points, and I kind of like those.
And there's Laying Down the Rails from Simply Charlotte Mason. The author has meticulously gone through Mason's series, extracting Mason's ideas about each habit and grouping her writings. She includes questions for reflection for the reader, and a few additional quotes about the habit, but there isn't much in the way of how to. More useful is Laying Down the Rails for Children which has explicit lessons, including short stories, poems, quotes, and ideas about what to include on sticker charts.
Here are three habits lists I've come across, including one compiled from LDtR:
Mater Amabilis (Training in Habits of Virtue)
Grace Online Library
Homeschool-Life (compiled from LDtR)
