The other book I'd recommend is The Pyramid Principle[2] by Barbara Minto.

Walking through the Abstraction Ladder with an example is a useful approach here. I'm curious if the same takeaways could be achieved in fewer words (it looks like the article is currently ~3,000 words). I've personally found the Pyramid Principle [1] to be a helpful starting point for determining which points I'd like to make within a piece of writing and then structuring the content around those, which may be applicable here, too.

To paraphrase some of King's advice:
"Read a lot and write a lot".
