I also think this would be a good method for someone who is ill or a woman who is dealing with the discomfort of pregnancy. Surely during the times we're in survival mode we can just do one tiny thing to improve a room. Just one. Pick up just one toy. Throw away just one crumb. Smooth out just one curtain.
Then, I started thinking of so many other one tiny things we could do. One tiny correspondence a week to someone who could use cheering up. One book a day read to our children. One effort of improving behavior. One Bible verse or chapter before bed. One way to improve our health a day. I think I'm on to something! One hour less (or 1/2 hour less or 15 minutes) on the computer or at the TV a day..... One more prayer prayed.
