As a high school student, I may not be qualified to give you any advice. After all, my own experience is still very shallow. However, when I saw your question, the first book that came to my mind was The Promotion of Du Lala. Maybe you have read this book, but for a young man who has just entered the society, I believe this book will inspire you.
In addition to recommendation, I still want to say that experience and experience are accumulated by myself. Books may inspire you, but after all, they are only other people's stories. You can experience the joys and sorrows of this big family through personal experience. This is a process that everyone must go through. Maybe now you will feel very hard and want to give up, but please believe that as long as you pass this hurdle, you will adapt to social life more and more and gradually integrate into it.
Finally, I would like to quote a sentence I like very much: life is like a trip, what matters is not the destination, but the scenery along the way.
No matter what you encounter in the future, always remember that the process is always more important than the result, and the society will repay you as much as you pay, so recognize the world and love it.
