Benefits of the Sabbath

I've known this, but at times it is so much more apparent: Part of the beauty of keeping the sabbath day holy is the mental rest that comes from setting aside those aspects of the weekday life that cannot be 'worked-on' on Sunday. Being currently unemployed, I can completely 'rest' from those worries on Sunday. I could spend time 'worrying' about things, but if I can't physically do anything about it, why not just 'rest' from that worry and spend time doing those 'good things' that bring joy and happiness. Monday is soon enough to start worrying about the coming week.
