Indeed, not usually applicable to urban living. But the main points come through, namely, find a place to work where you can get away from life distractions and gear it so that it is conceptually/aesthetically separated from the rest of your life; then have some ritual which signifies when it's work time. Mark Boulton in (_Designing for the Web_) has a separate, work-only room in his house, and his ritual is to keep his shoes on during the day (work time) and take them off when he's done (home time).
