I know this is a rant. And I didn't want to read a wall of text.
I am sure it's good 😅

I always recommend using # headlines (h1)

### h3

smaller

To help others skim through easier & quicker

Personally, I think forcing myself to use headlines and thus categorizing things at least a bit, improved my writing. Not saying yours is bad, since I didn't even read this one. (sorry)
