This provocative lecture explores nine deeply ingrained personality traits that, while often overlooked or even rewarded in modern society, can be toxic to relationships, leadership, and personal growth. Drawing from psychology, real-world case studies, and cultural commentary, the talk examines how traits like chronic envy, pathological lying, manipulativeness, and unchecked narcissism subtly infiltrate everyday life. Attendees will gain insight into recognizing these traits in themselves and others, understanding their psychological roots, and learning strategies to counteract their destructive influence. A compelling and eye-opening session for anyone interested in human behavior, self-awareness, and emotional intelligence.
