Well, I did figure out the solution to my own problem. Also, I mostly like my line of work.
Also, "something you can literally change tomorrow" is very much wrong, for the usual obvious reasons: I couldn't possibly afford a 90% salary cut, and neither could my family. Given standard life choices, past a certain age your career becomes a shackle.
‘can’ doesn’t equal you likely would want to endure the pain of doing so, or that it would provide an overall net benefit… I chose that specific word for a reason.
Of course there are significant tradeoffs to be made, since there are infinitely many potential tradeoffs in life.
