People differ in their self-esteem, the intensity of their emotions, the variability of their moods, and their inner security. Some confidently do what they feel like, while others struggle with self-doubt. Some are hardly disturbed, while others quickly lose their balance, both positively and negatively. They feel rejected and misunderstood. Conflicts with superiors arise, and relationships are often exhausting. Despite a longing for peace and harmony, life feels like a constant rollercoaster. What are the typical triggers for such emotional tension? Why is it so difficult to change anything? What is the purpose of self-harm? What does dissociation mean? This book addresses the problems and peculiarities that lead to a personality type.
