You were making some great points until you lost it here.
I noticed you repeated some things I pointed out in the article (writing every day involves learning every day, writing every day builds a habit, etc.)
People for whom I wrote the article are finding some sense in it, and for me, that's the most important thing.
What I see is someone trying too hard to pick nits after they'd already made their points.
And oh, congrats on being a writer for 30-odd years (if it's true, you'd have been at it before I was born).
