Teachers can be a living example to their students. Not that teachers should look for students to idealize them. One who is worth idealizing does not care whether others idealize them or not. Everyone needs to see that you not only teach human values but you live them. It is unavoidable sometimes you will be idealized -- it is better for children to have a role model, or goal, because then the worshipful quality in them can dawn.
When you share your misery, it will not diminish. When you fail to share your joy, it diminishes. Share your problems only with the Divine, not with anyone else, as that will only increase the problems. Share your joy with everyone.Listen to others; yet do not listen. If your mind gets stuck in their problems, not only are they miserable, but you also become miserable.
