★ Comes with a custom "Brother Gu's 16-Type Observation Notebook," sticky notes, and blind-box bookmarks. More than a workplace book—it is a journey of self-discovery.

Why do some people thrive in the same job while others suffer miserably?
The answer usually lies not in the work itself, but in the match between personality type and workplace environment.
Using the 16 MBTI personality types as its framework, this book dissects the typical dilemmas each type encounters in the workplace. For example, when an INFP newcomer joins a company and discovers a massive gap between ideals and reality, gradually losing passion amid tedious, repetitive tasks—the author cuts to the core: "A great many INFPs are severely troubled by emotional issues in their youth. If these emotional problems remain unresolved, they can seriously impair work efficiency." At the same time, INFPs "are generally uninterested in how companies and organizations manage their operations, but they care deeply about the social phenomenon of organizations exploiting employees' surplus value and treating workers like 'cattle and horses.'"
Then there is the ISTJ accountant's dilemma: every day they face a world of "cold, clear, logical" numbers, yet the social dynamics of the workplace—"those sticky, invisible, warm-blooded power struggles"—make them "more nauseated than three consecutive years of loss reports."
The author does not stop at "knowing yourself." He goes further by categorizing troublesome workplace characters—sharp-tongued types, backstabbers, chronic talkers, pessimists, credit-stealers—and teaches readers how to identify and navigate them, rather than acting on emotion and slamming the door on the way out.
Built on the MBTI framework and starting from the point of "knowing yourself," this book transforms reading into more than workplace reflection—it becomes a journey of rediscovering who you truly are.
