interestingly, despite sleeping for 4-5 hrs for the past 2 nights, I find myself being able to concentrate better (although I am slightly drowsy, like halfway in a dream world, but alert enough to do work).
i think the mind shuts down other distractions (like too tired to bother about other things and thus becomes able to keep only one strand of thought at one time) and thus it becomes easier to focus? hahaha.
i was doing a stream of consciousness exercise the other day (in which you just write down whatever comes to mind in 5 mins and continually write it out), and i realized that i had 2 streams of consciousness going on at the same time (which is pretty interesting because one stream would be the thought stream, whereas the other is the metacognitive stream which will analyze and comment on my original thought stream). whereas for now tt i'm tired, there's only 1 stream of thought.
on the addforums, it seems like almost everyone is simillar to me in being night owls (like being able to do work so much better at night, especially midnight to 3am or whichever. haha).
