From my perspective, you, sir, are more like a god than a superior. However, it seems many people in the world struggle with how to deal with their superiors. This book, "Treat Your Boss Like a Customer," which was in your collection, sir, was written by Keiichi Kaya, who often appears on TV talk shows these days. It's a book that offers a perspective for business people to succeed in their careers. This book centers on the idea that "boss = customer," arguing that company employees should act not just as employees but as "intrapreneurs" who provide value within the company. The author, Mr. Kaya, points out that a common trait of people who get promoted is that they have the mindset of "using the company" rather than being employed by it. By treating their superiors as "customers" and considering how to provide value and be evaluated, they can build a more free and fulfilling career. The book also explains how to navigate the company and specific strategies for achieving results, making it particularly useful for those who "want to get promoted" or "want to improve their evaluation." Perhaps you, sir, also devised ways to deal with your superiors when you were younger. Since you have allowed me to list this item, I will deliver it.
