I work on paper only and iterate drafts of jots, outlines, and mindmaps until I have all the main parts/ideas on a single page (ideally; sometimes 2–3 pages).

I do that until I can look at the entire thing at once; see that all the important parts are there and in the right order; see that no non-essential parts are present; and have it all make sense from a bird's eye view.

Only once that's done do I move it over to the computer and finish working with it there.

Same here. There's no insights to be gained writing code that I couldn't have had iterating on paper (and possibly showing to users).
