Written as a sequel to the international bestseller The Courage to Be Disliked, this book delves deeply into how we should live our lives. Millions of copies of this book have been sold in Japan. Like The Courage to Be Disliked, this book also has a dialogue between a philosopher and a young man, on the lines of the dialogue between Socrates and his disciples. The philosopher believes that Alfred Adler's theories tell us how to live a happy and satisfying life. Adler was a great personality in psychology in the nineteenth century, who was forgotten and for a long time was considered less important than his contemporary Freud and the era. The young man is skeptical about whether life can really be made better by just changing one's thinking. The philosopher very patiently explains to the young man the essence of Adler's 'psychology of courage' and explains the necessary mental measures to be taken to achieve it and clarifies how it can bring changes in the way we live our lives. This book truly has the power to change lives and is universally applicable.
