Re-reading your post, I would say it comes from implied disagreement with your deprioritization of the right tools. You also use the word system a lot in the essay, which mentally translates to tool for a lot of people (myself included, if I’m not careful.) It’s also hard to do more than mildly agree or disagree with GTD and energy management principles. I also suspect anyone disagreeing with your main point, coming into this thread to insist they can remember everything to do, would be attacked. I agree more variety in the discussion would be nice.
