Everywhere I go and everything I do I try to leave things “better” than what they were (I know what you mean about using the term better, but I think people have a general agreement about what better is in many situations.) If not better than at least unchanged, definitely not making thing worse. A simple example of this is anytime I eat out I clean up the area where I was sitting, often times leaving it looking better than it was when I got there. It’s really easy to live by this code, it only creates a marginal increase in energy output (if any at all) and makes the world a “better” place. That’s a small example, but it can be pushed out to include your work place, your neighborhood, your city, your state, your country, your world. I too think it’s better to focus on the micro level though.
