The sentence uses present tense with a clear subject-verb structure and an infinitive phrase 'how to live' as the object.
Schopenhauer's "The Wisdom of Life" explores how to live a life of happiness. Centered around the concept of "happiness," the book discusses the principles of health, wealth, fame, honor, well-being, and social conduct through three dimensions: "the self," "external possessions," and "how one presents oneself to others."
The book reveals the essence of life through these three profound insights:
1. A person is either vulgar or solitary.
2. Life swings like a pendulum between pain and boredom.
3. Mediocre people enjoy socializing and tend to accommodate others, as it is easier for them to endure others than to endure themselves.
叔本华的《人生的智慧》探讨了如何幸福地度过一生。本书围绕“幸福”这一核心，从“人的自身”、“人拥有的身外之物”以及“你向别人展示的样子”这三个维度，深入讨论了关于健康、财富、名声、荣誉、养生以及待人接物所应遵循的原则。
书中通过以下三句话深刻揭示了人生的真谛：
1. 人，要么庸俗，要么孤独。
2. 人生就像钟摆，在痛苦和无聊之间来回摆动。
3. 平庸的人喜好与人交往，喜欢迁就别人，这是因为他们忍受别人要比忍受他们自己来得更加容易。
