The principal welcomes students to a new session and encourages them to make progress. He congratulates those who improved their grades and tells others it's not too late to improve. He tells a story about animals opening a school to teach their children, but the children could only do what was natural to them, like fish swimming but not walking. The parents got angry at first but then realized the children could only follow their nature. The moral is not to compare yourself to others but to compete with yourself and improve. The principal wishes the students good luck and says perseverance, not luck, will bring results.
