PHILOSOPHER: All you can do with regard to your own life is choose the best path that you believe in. On the other hand, what kind of judgment do other people pass on that choice? That is the task of other people, and is not a matter you can do anything about.
YOUTH: What another person thinks of you—if he or she likes you or dislikes you—that is that person’s task, not mine. Is that what you are saying?
PHILOSOPHER: That is what separating is. You are worried about other people looking at you. You are worried about being judged by other people. That is why you are constantly craving recognition from others. Now, why are you worried about other people looking at you, anyway? Adlerian psychology has an easy answer. You haven’t done the separation of tasks yet. You assume that even things that should be other people’s tasks are your own. Remember the words of the grandmother: “You’re the only one who’s worried how you look.” Her remark drives right to the heart of the separation of tasks. What other people think when they see your face—that is the task of other people and is not something you have any control over.
