First, a minor point: The unusual font of this post (presumably because you wrote it in that font in a text editor and then copy-pasted here) take a lot of effort for me, at least, to read, and as a result I had to expend a moderate conscious effort to start reading, and found it nearly impossible not to skim or skip some sections. I imagine at least some other people experienced a similar effect.

Object-level, a very interesting post. One of my parents, who is quite similar to me psychologically, seems to have some narcissistic traits as described. They (sing.) make a conscious and explicit effort to avoid, e.g., excessive vicarious pride in their children or withholding praise except for highly exceptional achievements, and I think this has been pretty successful. But I have definitely noticed, in myself, unusually low empathy, high self-expectations and very excessive envy of exceptionality, to take a few. I predict that your recommended reading will probably improve my self-model substantially.
