The Courage to Be Disliked by Ichiro Kishimi and Fumitake Koga is a thought-provoking self-help book based on Adlerian psychology, presented as a dialogue between a philosopher and a young man. It challenges the belief that our past determines our future, asserting instead that we can choose to live differently at any moment. The book emphasizes personal responsibility, the importance of separating one's own tasks from others', and the idea that seeking approval or avoiding disapproval limits true freedom. Ultimately, it advocates for the "courage to be disliked"—the willingness to live authentically according to one’s own values, even if it means not being accepted by everyone—arguing that this is the key to a fulfilled and meaningful life.
