Emotions are contagious. When people operate from a reactive state of mind, they take on the negative emotions of those around them. This causes us to either suffer problems that are not our own, or to inflict our problems upon others because of our own uncontrolled state of mind. When we operate from a state of mindfulness, we bring calm and clarity to those around us. Maintain an immovable mind and exercise control over your environment by exercising control over yourself.
