Dunno if I would say I've become a good coder.
I regularly see stuff written by others and think, holy shit I couldn't manage that.

But somehow I've built a career out of people telling me what they need and me producing solutions for them. So they pay me.

I'm fairly personable, ask questions, listen to answers, when I fuck up (which is still just as often as 15 years ago) I take responsibility.

On the tech side, just keep doing it. Tackle one problem after another. Ask others and of course:
