Starting from psychology, this book pointedly points out the root of the fragility of the "glass heart" and focuses on methods to overcome fragility: overcoming perfectionism, resolving anxiety, controlling fear, regulating shame, reducing sensitivity, improving stress resistance, and building spiritual support. The author injects his own observations and research into each vivid case, and each chapter explores a topic in depth to help readers identify flaws in thinking, reflect on the current situation of life, and get rid of behavioral misunderstandings. Through intentional cultivation and practice, I believe that everyone can get rid of the "glass heart", improve the probability of success in doing things and the happiness index of life, and give life a more sense of direction.
