IWSG Aug 2025: Writing Habits

I have some writing habits that I'm mostly trying to break but it's easier to say you're doing it than actually doing it. But I'm trying, probably too slowly.
    One habit is using the word so. I don't use it as often in my fiction writing but on my blog, I may have used it too often. So is a very see-saw word - sometimes it sounds right and other times it sounds a bit childish. Another is run-on sentences - I don't actually think it's wrong to use them because people have a way of thinking that they sometimes do not pause in between thoughts but I guess in writing, it would seem wrong because periods allow the reader to get the meaning without having to figure out where a thought begins and where it ends.
    Sometimes it's a thin line between what is writing style and what is correct grammar. There's an author who does not use quotation marks and people love that author's books and editors and publishers are certainly not correcting them so is this a style or a bad writing habit? In a way, habits that we associate as being bad can be a style of writing.
    I think people are brought up in certain ways that their language in thinking and writing is a certain way that becomes habit. We can't stop our habits just because someone or a whole bunch of someone says it's bad or wrong. But I guess in terms of grammar, what's wrong is wrong but is it wrong? We are used to other people's standard to judge our own habits. Even if you are good at making your own judgements and even think you are an independent thinker, it doesn't mean you aren't influenced by others.
    It's not easy to unlearn habits you have formed and kept for a long time. I certainly don't want to lose all my habits (good or bad) because they are hard to lose and because I like some of them.

What writing habit (or habits) you think are bad but still use?
