I'm not sure what TFA means (the first article), I appreciate being called competent, though the truth is that I'm just less blundering than some other people.
I'm here because there's some path-dependence in careers. I started at a mediocre company due to not having a permanent work visa, and have been clawing my way up. I should write something else on this, but I've also realized clawing my way up was unnecessary - it turns out that while I've had some skill atrophy from working at these places, good engineers recognize someone that isn't going to cause a spreadsheet dumpster fire, so I should have just jumped to one of the top rungs on the ladder years ago.
