Hm-m-m-m... I'm not sure I really understand the concern here. If you're working, you're working, & if you're relaxing you're relaxing. It seems to me that would be a good thing. Too many people "take their work home with them", so to speak, by which I mean they ruminate over things that happened at work to the point where they can't really relax. So if you're saying you're able to focus on work while you're at work, but when you relax you're able to fully relax, that seems as though it would be a lot of peoples' dreams. Beyond that, I'm afraid I don't know a lot about self-discipline. I just know what I have to do... & I do it...
