Have you ever awakened and not felt like yourself? Or wondered why someone you're talking with does not seem to get it? Or why conflict often only worsens despite our best efforts? Or why another culture seems so different? How we behave in private and with others is a rich mix of factors. Our preferences -- laced with our motivations to seek gratification even in conflict, topped with national or cultural personality traits -- influence how we interact, and what we do, each and every day. We can learn about these, and how they influence others.
