Live and Let Live

Every human being has a tendency to worry about the other fellow. It is a characteristic which none of us seems able to control. To be able to live our own lives without worrying about the other fellow is a virtue few of us possess. I have noticed in myself a feeling of depression when a friend of mine was driving a new car. I felt inferior because my friend had something I could only wish for. Is this not the pattern most of us follow in our lives? And isn't it also true that we many times concentrate on things which are of no concern to us; thus find ourselves in a "jam" because we didn't pay more attention to ourselves?
