The first rule of ethics is “do no harm.” The second rule is “do good.” These are well established principles or pillars of thought that, when adhered to, wisely guide both personal and professional behavior. Although this list is profound, it appears lacking. 

We all know that regardless of our best effort, eventually, intentionally or unintentionally, we will cause another person to feel harm. When this happens, a third pillar is needed - “When harm is done, as quickly as possible, undo it.” 

When “undoing” does not occur, the harm lingers and pain deepens. Stated another way, you may think that when you have harmed someone things couldn’t get any worse. You’re wrong. Without putting forth effort to undo the harm, a memory of being forgotten, uncared for, or worthless is laid down.

Therefore, make every effort to avoid harming another person by concentrating on doing good. But when you do cause harm, make yourself memorable by focusing on undoing harm.
