Office manager, salaried, two girls, 8 and 3, and we own a home. I start my day at 5, at my desk by 5:10-5:15, I do a working lunch, and Im off around 4 pm. At that stage, the girls are home, or I may have to get the 3 year old. Once we are they, we prepare and eat dinner. Do dishes. Spend a little time with family.
Then mix in laundry, garbage, grass, errands, etc.
Once the girls are bathed and in bed, its usually 9-9:30, and Im usually staring down less than 8 hours of sleep before I do it all again, not mention taking mine own shower.
Even if I want to watch a show or play a game, I usually am nodding off within 5 minutes because Im running on fumes at that stage. So... zero.
