Buy paper plates and cups. You can eat your dinner and then just chuck the stuff into the trash. Since my husband has to work out of town on many weekends, this has helped me keep those dishes from piling up. Make simple meals. You know there are going to be days when you don't have the energy to cook dinner.
Many grocery stores have meals that are already prepared.
Some of these include stir fry meals that you can just plop in a pan and heat. In the morning, when you have the most energy, you can toss the ingredients in and it will be ready by dinnertime. Use throw rugs and runners. I hate mopping. It's the worst.
