Single dad, night-person here—I far prefer working at night once the kids are in bed over trying to squeeze meaningful productivity in between school hours, dinner, activities, father-son time, etc. I've trained myself to do something from 9-4, as those are my remaining school-age son's school hours, but it's nowhere near as satisfying as working at night when the world is asleep.
