Again, time management. For me and my husband, weekends are usually the best time to socialize with our RL friends. During weekdays, it's usually too late and we're too tired to go out anyway so it works out nicely. We'll make dinner, clean, spend some time together, and then spend a few hours unwinding. When you have a set schedule, you figure out what to do when.
I also don't play every day of the week, either. Keeps me from getting burned out.
