I'm in a routine of working roughly 9 to 5, actually it's more like 10 to 4 but anyway
Unless there is something very important that can't wait until the next day I tend to stick to my routine. My wife gives out to me if she catches me near anything work related in the evenings so that's probably a good thing. It's not good for the eyes to be stuck in front of the screen for too long anyway. Although I do like to try and take a sneak peek at the forums and read/research in my spare time if I get a chance.
