I can never do the "rub your tummy/ pat your head" thing. Or is it the other way round? Pat your tummy and rub your head? I'm sorry, I know it's pathetic, but no matter how hard I try the rubby hand starts patting and the patting hand starts rubbing. And before you know it I'm doing some weird morris dancing thing like Peter Crouch celebrating a goal or a middle aged man at his daughter's wedding disco. Perhaps the Mem is 100% right - men are no good at multi-tasking.
It can be the same with writing. Just when I think I've got this adjective/ adverb things nailed, along comes dialogue and grammar. So I try and get that right, and then I find that my plots and ideas are wrong. Then someone says "show not tell" and that's another thing to think about. And ...
Sometimes you just need to hit pause, pour yourself a cup of coffee (or whatever hits the spot for you) and take some deep breaths.
Writing isn't one skill - it's several. At first it looks easy. You simply plonk your fingers down on the keyboard and words happen. But then you find that it's nowhere near as simple as that. The really good writers make it look much easier than it really is.
At this point, I've got some good news and some bad news. The good news is that the different elements that make up writing aren't actually that difficult. Anyone can learn them.
The bad news is that, like all that rubbing and patting, the real art comes when you start to pull all the different elements together.
What to do? You conquer writing the way that we first climbed Everest. One baby step at a time. Don't worry about the plot when you are perfecting your writing style. Don't worry about your writing style when you are working on your characters. Make lots of mistakes, put lots of words on the page, but focus on one thing at a time. Don't worry about the bits you can't do yet. They will come.
One final thought. There's a bit of management theory which might help. The clever management gurus who talk about management as a proxy for actually doing it have come up with this natty little progression about how anyone learns any skill.
At first comes
unconscious incompetence. We are not very good at the new skill, but we don't know that.
My writing looks perfectly brilliant to me.
Then comes
conscious incompetence. We learn enough about the new skill to know that we are not doing it right yet.
Uggh, my writing sucks.
Next,
conscious competence. We know how to do it, but it takes lots of effort and thinking about.
My writing is pretty good when I work at it really hard.
Finally, we reach the nirvana of
unconscious incompetence. We have mastered the skill to the point at which we don't have to think about it any more.
I find I can write pretty well in my first draft, although I am not sure how I do it.

From the OP, my guess is that you in stage 2 - conscious incompetence. That may sound a bit negative, but it's a hell of a lot better than being in stage 1. And stage 3 is just around the corner ... as soon as you learn to pat your tummy and rub your head.
