The article summarizes Alfred Adler's book, Self-Esteem and Transcendence (《自卑与超越》), which introduces his Individual Psychology. It explains how feelings of inferiority and the pursuit of superiority motivate individuals to overcome challenges and grow. The text emphasizes that personal experiences do not predetermine one's destiny, as individuals can creatively reinterpret their past and set future goals to change their behavior. Ultimately, it asserts that the meaning of life lies in contributing to society and fostering cooperation in various aspects such as career, interpersonal relationships, and marriage, highlighting that human problems are fundamentally problems of cooperation.
