I think you know best what you need and how you work most effectively, and that you can and should do it JUST LIKE THAT.That's what I do, anyway.
Different "rules" for different kinds of writing, too, me. Grant-writing hell is one thing, lyrical meanderings are something else. I don't always know what will be best, till I have given into my instincts, done the thing, and then looked back. So you might want to think about whether you have several modes, each needing its own ambience, approach, and affect.
Try doing it just how you want. You'll notice whatever is not working, and then adapt that.
