I was forced to torpedo a previous career because a relative got sick, and then I got sick...moving to the city wasn't a good idea but the only choice in that industry, so I had to move on (I grew up in the city in question, utter hellhole, commutes are horrendous, I would have moved because I loved the work but that was all).

Obviously, I have a biased perspective but what frustrated me wasn't the loss to my own career. I just got on with it, retrained, moved on. But the fact that I had useful skills, had spent years developing them, and the most rational thing for me to do was to literally start from zero in an industry that was more accommodating...which seems a bit silly.

So I wouldn't even frame this as a personal thing. The reason the career development opportunity is so large is because the opportunity for employers is so large...and, ofc, they are the ones resisting this.
