This. We have activities every day of the week. I still read aloud to my kids, and our academics are rigorous. My house is clean, the laundry gets done, and I cook every night of the week except Wednesday, when we eat at church.
How do I do this? I get up early and go to bed late. I multi-task, like putting dinner in the slow cooker while I'm making lunch. I go, go, go, when I would rather stay home. Why? Because my kids thrive on this kind of activity. I can rest when they're grown.
