A Korean psychiatrist wrote a hit song about self-esteem.

A Korean psychiatrist has written a best-selling book on self-esteem that has captured international attention. The Self-Esteem Class, authored by Dr. Yoon Hong-gyu, has become a publishing phenomenon in South Korea, with over one million copies sold domestically. An international edition was released under the same title, finding readers far beyond the country’s borders. Dr. Yoon's work stands apart from typical self-help books that often rely on complex psychological jargon or grand promises of transformation. Instead, he approaches self-esteem through everyday situations that are easily relatable. His narrative is grounded in personal experience, which adds authenticity to his insights. In the introduction, he dismantles the traditional distance between therapist and client, presenting himself as someone who once struggled with self-doubt. He describes growing up as a sensitive child who did not stand out socially, lacked confidence, and faced academic setbacks during medical school. These experiences later fueled his interest in understanding how self-worth influences life satisfaction. His central thesis is simple yet profound: the way we perceive our own value significantly affects many of our decisions, even though we may not always recognize this influence. Rather than reducing self-esteem to the cliché of “loving yourself,” Dr. Yoon explores its complexities. The book is divided into seven sections, gradually shifting from theoretical explanations of self-esteem to practical scenarios that mirror real-life challenges. It addresses relationships, the need for external validation, fear of relationship endings, feelings of inadequacy at work, indecision, comparisons with others, and dependency on others' opinions. A special section focuses on emotions that hinder healthy self-relations: shame, emptiness, ambivalence, self-loathing, guilt, self-pity, disappointment, resentment, and cynicism. These emotional barriers are explored in depth, offering readers insight into their internal struggles. Later chapters examine habits that undermine self-esteem, expecting failure, lethargy, feeling less valuable, procrastination, and avoidance, before introducing more concrete strategies to break these patterns. What makes the book particularly engaging is its ability to make readers feel personally addressed. Many reviewers have noted that they recognized themselves in Dr. Yoon’s examples, especially in his vivid metaphors and real-life illustrations. One reviewer praised the way he connects seemingly unrelated behaviors to questions of self-worth. For instance, why is it so hard to make a decision? Why does certain criticism affect us for days? Why do we stay in relationships that don’t serve us? Why do we need others to confirm our success? These questions give the book a unique edge over conventional motivational texts. Each chapter concludes with small exercises designed to help readers apply the concepts directly to their lives. Unlike some self-help books that present these practices as miraculous solutions, Dr. Yoon frames them as gentle nudges toward action. Readers are encouraged to engage with the material actively rather than passively consume it. Some have highlighted the importance of these exercises, noting that while reading alone can offer inspiration, true change comes from consistent practice. One reader emphasized the significance of the chapter on unconditional acceptance and love for oneself, calling it a standout section. Others have appreciated the gradual structure of the book, suggesting that it is better read in smaller segments rather than consumed all at once. This approach allows readers to reflect on each concept before moving forward, reinforcing the message that self-esteem development is a process, not a quick fix.
