Treat work like work, and home like home. Don't allow them to bleed as a hard rule. Covey was right - get dressed for work, every single day. Have a work area, a work pattern and never do anything personal in that space. When I lived in a small space, I used a laptop desk for work, purely to separate the two. The mental approach is enormous. Enforce some form of hard separation. When work ends, don't get up and make dinner (unless that's an hour long activity). Shut things down, go for a walk, call X, play guitar, play a video game... basically do something to ensure you're completely changing from one mode to the other.
