This study aims to determine the meaning of failure from a book entitled "Read this book when you fail: pretending to be successful is tiring" by K.L Rahayu. This book explains how to take failure and turn it into success. This book also provides knowledge of who we are, and various ways to know ourselves to achieve true success. This study uses a qualitative method, namely by deciding conclusions by outputting data and also focusing more on the morals and messages of this book. The results presented in this study, if you feel a failure, then immediately collect your spirit and throw away negative thoughts to quickly return to repairing things that have fallen apart. Failure should be considered a friend, so it will change bad things for the better and more colorful. A person's success is the product of a failure, therefore failure should never be considered the end of everything, instead, it becomes a big opportunity in the next step.
