So, the rating (we start at 5 stars):
+1 star for some cases included,
-1 star for the cases not being MECE, not anywhere close,
+1 star for quite a lot of ground covered, even if in huge leaps, maybe it's even going to a be a reread,
-1 star for a lot of stuff not detalised into demonstrable detalization,
-1 star for a lot of concepts left unlinked with practicalities,
+1 star for insights included, there were some, even though these were very generally formulated,
-1 star for the abstraction overused - while I love a lot of this stuff, I'm pretty sure somewhere a little management consultant cries bitter tears reading this, since this style overruns is precisely what gets professional consultants' panties in a twist, I think this would have been a plus for me years ago, before my brain got into all the don't-boil-the-ocean, SMART(-not) mode,
Overall, it feels closer to 3 stars. But the grading system says it's 4 stars. Let it be 4.
