I don't love any of my Hubs. I do have some that I like and that I know are my better writing than some others. For the most part, what does well with traffic and what meets my standards for "better writing" aren't the same thing. So, the Hubs I like best aren't usually (if ever) the best performers. I don't see the non-performing issue as a reflection of my writing because what does well on the Internet isn't particularly a matter of what is most well written.
I'm pretty good with being objective about my own writing. I can see when I've been sloppier in one way or another, or when I've done my usual thing of "slipping into blah blah". LOL There are a few other things I know I tend to do, and I see them happening as I do them (and yet I keep going anyway, because stopping will throw off my train of thinking). Anyway, I'm pretty objective once something is finished. What I'm not objective about is being able to trash my mediocre stuff once it's all written. I should, and I don't.
Of my Hubs, only a small percentage meet my own standard for my own writing. I'm confident that those that do meet it are decent writing. Whether readers appreciate them or not, I don't really care. I like them. Conversely, with the stuff that makes me cringe because it's so flawed and/or mediocre, all the readers and traffic in the world wouldn't make me see it in a more positive light (as far as writing quality goes). I don't think good quality writing is at all subjective any more than correct answers in math are. Someone may not like the subject, but the quality of writing is a "technical" thing, even when it involves elements of emotion or something else that isn't "black-and-white and technical" in the piece. There can be a piece of writing someone isn't interested in or doesn't like; but it may still be a good piece of writing (as opposed to a mediocre or worse piece of writing).
I guess I'm confident in my own understanding of the technical aspects of writing, and aware enough that no piece of writing will be liked by every reader, that judge by what I know and can control - and leave whether anyone likes the writing or not up "the four winds" (as my mother used to say). I can't worry about who likes what. I'm already dealing with the fact that I don't like most of what I have on here (which I started doing so I could write "more casually" - but which I don't like because I don't like "more casually"). I like "formal" and "technically correct" and "professional"; but because this a spare-time thing for me, I need "more casually" sometimes. (I just don't like it once it's written. LOL )
