I like this author--he's involved in a number of worthy projects, such as assisting soldiers returning from war and working on racial trauma.
This particular text is fine. It takes some ideas familiar otherwise (such as the primary point that confrontation is necessary for qualitative development, which seems reasonably hegelomarxist) and applies them to domestic management. I didn't care much for central Frankenstein conceit, and the buddhist-sounding 'five anchors,' which are the principal technique for making use of confrontations, are mentioned early but explained late, and perhaps too thinly.
The main objection to them and overall here is my normal objection to popular psychology books: the normal layperson (i.e., me) can read the words and be deluded into the belief that the words have been understood, a regular dunning-kruger operation. Use of the psychological knowledge very likely should be subject to an experience derived from proper instruction backed by clinical correlation. Otherwise, such texts can be perilous. That is, the text itself is not harmful, but dumbasses can do harm with it.
The case studies/examples contained within the argument are illustrative and compelling, but that's the effect of trojan horses.
