We all hear of the dangers of perfectionism. You are just supposed to get your stuff out. There is a problem, though, with never having the feeling of having done something really well, of having gotten a piece of writing to the point where it hums along flawlessly. If you haven't done that at least once, then you won't know what if feels like and won't be able to reproduce that feeling again. I admit there have been times when I felt less fussy about style, but the times when I paid more attention to writing (most of the time) made me a better writer and carried me through those other periods. What I consider my badly written pieces are still better than a lot of yours are. There is no such thing as writing too well. I cringe when I find a bad sentence I have written in a published book review or article.
Some people's writing seems overly fussy. That probably is a good thing, for that sort of person. As a reader you understand the ethos of care for writing that went into that sort of style, and the results are unlikely to be bad. I would rather be eloquent but looser, taking a few risks, but, once again, that's a personal preference, an expression of my particular ethos of style. I could even go back and make sure I have at least one swear word, one preposition at the end of a sentence, and one sentence fragment in something I wrote. I'd rather use and interesting word when I want to, at the expense of smoothness. The blog lets me write in a fun way, with some eloquence, I hope, but with less fussiness.
