It is true that some people may have a greater sphere of influence than others, but there is no one who has no influence at all. We all have some influence or effect on other people. That influence can take different forms as we live our lives. We influence others with our speech, with our actions and with our lives. People listen to what we say and how we say it and what kind of person we are. They see what we do and determine what is important to us. They may look at our lives and modify their lives based on what they see in us. We will have an influence on others.
