When I'm actively working on a project (which now is most of the time), either for myself or for a client or family/friends, I probably average 6-8 hours; otherwise maybe 1 or 2. My wife is still working full time, so I do most of the errands, chores, cooking, etc., in addition to most of the yard work. I teach a class at a local university during the spring semester; TIS drops way down then.
