A student suddenly forgot the answers to all the questions while taking an exam. He sat there in shock with the question paper in his hand. Despite trying hard, he could not remember anything. Finally, he plucked up the courage to go to the teacher and said, “Sir, the answers to the questions have escaped my mind!” The teacher smiled lightly at his words. He said, “The answers do not escape, we cannot remember them because we do not prepare properly.” The student was embarrassed, but at that moment he learned a big lesson—success cannot be achieved without hard work and regular study. From then on, he decided to study hard.
