For teenagers, I think Liu Yong's book is good, because it is easy to understand and impressive. For example, I'm not teaching you to cheat (1-4), you must know human nature, succeed in one step, affirm yourself, surpass yourself, break through the glacier of life, the truth of life, be a happy scholar, whisper in the firefly window and so on. In addition to our common magazines Communication and Eloquence, Speech and Eloquence and The Beginning of the World, there are Carnegie's series of books, Advantages of Human Nature, Weakness of Human Nature, Beautiful Life and Happy Life and For Girls, which can make you tolerant and happy, and are compulsory courses for young people. Napoleon Hill's success is a magic weapon for office workers, and the wisdom stories in vernacular think tanks and Romance of the Three Kingdoms are more inspiring. Most of these books can be read online. Sina reading and Tencent reading are both good.
