Spiritually Speaking - What's a good quote you can live by?

"The world is my family." It's from ancient India. I meet people from many countries in my job & enjoy getting to know them. Also, I've done the math that shows, given the world's population & the number of available ancestors, then chances are, we all come from the same ancestors & are distant cousins. So, it's good to treat everyone like family (or nicer) because they are & try to see the world from the point of view of others around the globe.
