While doing a last minute revision of anything, I have realised that creating latex documents(or using any other document preparation system) makes things more clear and finished than writing on a notebook. Nothing mysterious but maybe it depends on how much freedom we give to ourselves: My notebooks are usually messy, have thoughts in all directions and conclusions in less discrete form (because of happiness of reaching to those conclusions). Revisions are more about being final and clear and not roaming anywhere and latex makes it hard to roam.
