We seem to hardly be able to keep our head above water at times. I thought homeschooling would help, but it hasn't really. And as I've thought about your question this weekend, several ideas have come to mind. These are mainly theoretical, because I tend to be able to make life changes by first thinking and praying about why I'm doing something now, and asking God is show me the right mindset on that issue. Having lived in several cultures that have a slower pace of life, I agree with you that life here does seem so hectic.
American society has so many options.
When we lived overseas, the choices for entertainment were limited. So there was time to sit on the steps and talk with a neighbor while the kids played out front. Here, there are things to do around the clock. It is hard to say NO to everything, or most of it, at least. You are expected to be busy.
