I've come to believe that the primary elements of writing advice are anecdote and metaphor. Because writing is an art form, and art is both individual and mysterious; thus, anecdote and metaphor. We can't say what writing is, we can only say what it is like. For us.
The essay is fine. Like all such essays, it's going to speak to someone because it comes along at just the right time for them. A thing doesn't have to be universally and eternally correct for it to be useful.
My complaint isn't with the subject or the author but with the magazine. Specifically the editor (I'll blame them) for the title and subtitle, which together conspire to lead the reader to believe whatever truths lie within are in fact both universal and eternal. I get it. You aren't going to lure many readers with a title that says: "here's one guy's impressions of what works for him, maybe you'll find something worthwhile, do please stop by and maybe subscribe." But that's how it should read.
For myself, articles like this just never seem to be talking about whatever is bedeviling me at the moment. Right now, for example, I'm trying to resolve a plot hole in a (fantasy) mystery I'm writing. Timing, character, even physical geography, not to mention world backstory and how magic works, all enter into it and it has nothing to do with writing scenes while having everything to do with writing scenes. Where is the blog post that talks about how to let the reader know the villain's scheming when we never see the villain's POV? Or which of a dozen different ways of conjuring (gesture, song, chant, wand, etc) is the one to choose for the murder scene? Realist writers have it easy. Gun. Bang. Dead.
Ah but now I'm just whining. I hope the OP finds something worthwhile in the essay.
