“only blocking out every thought that had ever previously occurred to him” This is the one part that I’m kinda unsure about. If you mean “don’t just loop through the same line of thinking over and over with no progress”, than sure, but being too strict on that may prevent further/alternate development from a line of thought. ie, taking a notion from earlier farther or in a different direction than previously. (or did I misunderstand?)
