Could spend some serious time on each of your points. Goes without saying that your article is a master class for short story writing. I said it.
Most of what you said I'm familiar with, of course, I mean I've been a struggling writer for many years. But! That's just it. It never gets rusty, the teachings remain fresh.
The way you've packaged your thought out observations injects a freshness into the subject of writing, congrats. I might add, this not an easy feat as there is a storm of stuff 'out there' on this thing we call: writing.
Makes me want to pick up my favorite pen or glitch infested lap top and get going.
Thanks again for an excellent piece.
