How can I serve them, enjoy my own achievements, and let myself revel in happiness? Sometimes I am tired, but I feel more like I am growing up. After that, I obviously find that I am cheerful. Although my own strength is not enough to change some things, if more people and the whole society work together, this is the root of my strength. On the other hand, I know I lack experience and eloquence. To be honest, I'm not sure what this means. But for a college student, it is a basic quality to dare to accept challenges.
