Normal fear is healthy. It paves the way for one's progress. It preserves life. A Headmaster is afraid of the Inspector of Schools. He takes a very keen interest in training the boys. All the boys get success in the examination. An engine-driver of the Railways is afraid of his superior officer. He is very careful in the discharge of his duties. No collision occurs. A physician is afraid of getting a bad reputation. He takes great care of his patient. He makes researches. He saves many lives. He becomes a famous physician also.
