Thoreau provided great insights in living off the grid long before we thought seriously about that idea. Living life based on a checklist of moral behaviour is nearly impossible. Living a life that we are good at is a growing experience.
We cultivate our lives like farmers and gardeners when we pay attention to our work, our living. It is in the moment that we realize and recognize the ethical needs. Certainly, there are rules to live by i.e. The Ten Commandments and The Three Universal Truths of Buddhism. When we live life and include those rules and truths, it is in living that we become who we are. It is in living we become good for something.
