Hey. Me thinks you need some cheering up or something. You seem to be doing a lot of introspection. It's not a bad thing but you seem to get more and more cynical as the days drag on.
Right now I'm married to my job. I go in around 7:30AM and leave about 12 hours later. I enjoy being there and I know I enjoy the act of "working"...but...I know I also find being at home miserable so I know the reason I stay as long as I possibly can is because I just don't want to go home. So...you may need to think about some of the other aspects of your life that may be driving you to bury yourself in work.
