I can relate to this article. I've found that waking up at 6am and going for a jog was a great way to start the day. Also, as a programmer you can lose all sense of time whilst pounding away at a project. My way of disengaging from that is going to the gym, the cinema or just hanging out with friends. You must be sure to not get lost in the start-up race and do things that have nothing to do with your start-up every now and then at least. Great article!
