One of the factors I was able to pinpoint was the speed difference between typing and writing affects this "evaluation" process. I'm not a fast typer by any means. ~70 WPM or so, however, this effortless typing reduces how I think while typing vs. how I think while writing. Writing is always deeper, and creates more sparks or lead for new ideas. Also what I write comes out more refined since my mind has to wait for my hand more, hence re-evaluate or evaluate further down into the path before my hand can write out what I have thought in the beginning.

Another thing is, even though I have a very good to-do system backed by a nice software and allows me to see what I'm doing forward in time (application is called Pagico, BTW), I always keep a notepad nearby and automatically offload some information onto it. I tried tons of fast-note applications. On-screen sticky notes, notational velocity and friends and whatnot. I always return back to pen and paper and live better with it.

Well, the notepad I'm currently using is labeled "#14", and this is after the fact that I started numbering them to be able to index them. So, by both trial/error and intuition/insight, I always return to pen and paper.

Same for my diaries. I have an encrypted diary on my computer, yet I still use my paper one(s), and the digital one is a backup in case I really need it, and I don't have the paper one with me.
