What stories end with an epiphany?

I have read such a story, that is to say, there was a little boy who was stupid since he was a child, and his academic performance was not good at all, but his deskmate was always the first. However, the little boy studied very hard, and his grades were at the bottom of the class, and he has been slowly improving, and then junior high school and high school are also the same. Later, he was admitted to the university with the first place in the school. As a reward, her mother took him to see the sea. At the seaside, his mother said this to him: "Look at the little finches and seagulls on the beach. When the waves come, the little grey finches can fly very fast, while the seagulls look clumsy, but it is the seagulls that can really cross the ocean. " This story makes me understand a truth: it doesn't matter whether you are stupid or not, but you must have endurance and be serious. The so-called diligence can make up for it.
