That's busy enough. See comments about working on someone else's schedule, first, then add in time for meals, commuting, showering, taking a dump, exercising, doing household chores, paying your bills, responding to email, etc.. After all that, there isn't much time left in the day. Especially since some businesses start closing down at night. You're probably tired, anyway. Those 9 hours at work make a HUGE difference.
