Such bold conclusions from 900 words and a single perspective. Isn't it possible that the author is, in fact, not good at the job?

People who are bad at their jobs usually fall into two categories:

a) people who lack the insight to realize it, and thus don't work to fix it b) people who realize it but don't care (for various reasons, some valid some not)

If you're agonizing over your job competence and trying to improve but feel you aren't succeeding, then it's vastly more likely that either your job specification is impossible, or you're setting unreasonable personal goals around your job.

I'm really bad at basketball. I have to insight to realize this, and I tried to get better. I really cared about getting better. But at the end of the day, I am not athletic. Sure, I can devote time and energy to improving my basketball skills, but I will never achieve anything beyond 'mediocre'.

There's also a chicken and the egg issue here; perhaps the author really does not enjoy coding and thus is not willing to put in the effort to improve?

c) people who don't have what it takes to do the job well (be it physically, intellectually, emotionally, etc...)

All sorts of things are possible from this post as from any other that one isn't in a position to personally verify. It's possible that the entire post was created by Mossad as an experiment in memetic warfare; not that that's likely, but I can't disprove it. Thus, as usual, my response has the implied precondition 'if things are substantially as the post suggests they are'.

Is self doubt ever about being bad at something?

[monochromatic]

Sure, sometimes it is. When I doubt my career skills, I can (usually, eventually) recognize it as insecurity / impostor syndrome / whatever.

When I doubt my dancing skills, it's a rational evaluation.

[imagist]

Yes, unless you believe that a) nobody is ever bad at anything, or b) nobody bad at something ever notices.
