This book was written with an aim to become a guide for introverts to embrace oneself in today’s modern society where extroversion has dominated and indoctrinated; and to explore the path that finally leads to happiness. The author, who is often mistaken for an extrovert although being extremely introverted inside, made the most of his personal experience and intends to present a path to become a Skilled Introvert who is aptly trained in society. Once you embrace your own introversion, you can go on your own way without being wavered by external factors. In addition, traits such as ‘Expressing how you really think inside without any difficulty’, ‘Being good at self-promotion’, ‘Being good at saying No’ etc., that are often perceived to belong to extroverts or as innate weakness of introverts are in fact, skills that can be acquired. Therefore, I wish to convey a message that introverts do not need to force themselves to become extroverted, and instead, embracing one’s own introversion is critical. There is nothing wrong to be an introvert, and it takes different shape of efforts between an introvert and extrovert to lead to happiness. This book addresses various approaches to building the five components mentioned above. Furthermore, it introduces interpersonal skills that can be practically applied to human/social relations right away. The nine interpersonal skills it addresses including ‘The skill of conveying your thoughts’, ‘The skill of saying No’, ‘The skill of small talk’, ‘The skill of coping with rudeness’, ‘The skill of comforting’, ‘The skill of self-promotion’, ‘The skill of being a good presenter’, ’How to maintain attractive posture and attitude’, ‘How to recover from daily frustrations’ will help you become more mature in socializing.
