I have here some 10 year old C++ code I've written lying around. It's pretty terrible style-wise, but not as bad as I imagine it to be without looking at it.
But the main point is that it worked in production for years. I would have written it much better today, and it will probably work faster and be easier to maintain. But it would also probably take longer to develop (though less time to debug and stabilize) - and ultimately, it would do the same work in production.
I'm not saying that improving your coding style and skills is not important. Just that we need to keep our eye on the ball - which is delivering working software, not code.
