I work Mon - Fri 8+ hours a day. As long as I'm in the office before 9 AM and work for at least 8 hours I'm good to go. If it's a slow day I work the full 8 hour, and if it's busy I stay to get as much done as I can. Add an hour to two hours for commute each way based on traffic and that's my regular week.

Occasionally I'll add night classes, but haven't done that in a while. Should probably go back and finish a degree.
