Many situations in both professional and everyday life require assertiveness. However, people who struggle to assert themselves often end up at a disadvantage: they are more frequently taken advantage of, and are less likely to be taken seriously or respected than others. This guide shows readers how to increase their assertiveness and better achieve their interests and goals. The author of this book focuses on individuality. He first inquires about personality types, personal motivation, and subjective perception. Only through a thorough self-analysis can one become convincing as a person and influence oneself. Subsequently, the techniques of body language, communication, and manipulation are clearly described. Readers will also encounter very critical phases that they must master to improve their social skills.
