Its strange.
I have this job where I have to do the same task over and over again. I like my job - (I don't like the fact that its moving to NJ) but I do like my job. I get to do basically whatever I want, in silence at my computer for 8 hours. My point? I was just doing my "task" and found it to be rather... soothing?? I got some actual thinking done. It was like going for a jog in a way.
