I'm not only trained as a clinical psychologist. I also have 14+ of experience as a professional engineer and a manager/leader, with an MS in electrical engineering. So I'm viewing this as someone who worked an individual contributor, a technical leader, and as a manager, and then went and trained as a clinical psychologist, and then came back to engineering. I also coach leaders.
The GP is suggesting that you add "reader, writer, and editor" to your credentials. Not that I give one single care about any of them.
The middle section could pretty much describe "anyone management doesn't like that doesn't completely give their life to the company". It equally applies to the sociopath as well as the talented person that isn't excited by your business plan of selling ever-more paperclips.
Any knowledge or skillset can be misunderstood and/or misapplied. I'm doing my best to express my understanding, which may, of course, be completely wrong. I've also been doing my best to understand this stuff, which included taking a long break from engineering work to study it.
