I work during my commute. I have a 3.5 hour daily commute with 3 of those hours on the train. I'm the first stop both ways so that gives me freedom to pick my seat. I find a seat that has an electrical outlet on it and then pull out my laptop and go to town. I get a lot done because I don't have any distractions.
When I'm home, I just try to find time when my wife is watching TV as I want to spend time with her and have the obligation of dogs.
