You know when you're thinking about many things at the same time or just thinking about the same thing over and over again, then maybe sometimes one subject leads to another and you end up thinking about something which can be totally irrelevant to the original subject ...very confusing as is.
But what makes me write this post, is that feeling I get when in the midst of all this, my mind just suddenly goes blank..and I have to start all over (if I still got the energy).... frustration is definitely an ingredient .
It's like after you've worked so hard on that file, your computer suddenly restarts and you end up losing all your unsaved data..
Maybe the computer is overworked...
