Treat people well. Every human knows inside themselves that this is a vital ethic, but we so often forget how vital it is. When we allow spite to creep into our conversations, we slowly chip away at the respect we feel for others, and the respect they feel for us. Trust evaporates. Relationships dwindle and disappear. Treating everyone (whether we like them or not) with respect and positivity can do nothing but improve our lives. Not all people will return the favor, but enough will to make it worth the effort.
