Last month I shared research that showed those who are the most successful in leadership, relationships and marriage are those who are not afraid to step up, address and discuss sensitive issues with others. The struggle with sensitive issues is that they are often very emotional and generate our age-old evolutionary response: fight or flight. That defense mechanism causes us to use ineffective methods of communication. When we are loaded with adrenalin, our brains lack the necessary blood flow to remain calm and think clearly.
