How do you juggle work and family time?

I try to be efficient --- when I'm at work, I do my best to focus so I work faster and can go home without worries. When I'm at home, I shut out work completely so I'm 100% with family. This way, I don't waste time. Of course things can't help but overlap but it's nice to keep the concerns separate so I won't feel overwhelmed even when I have a full day.
