Before reading, write down the purpose of reading this book; After reading a book, write down what you get after reading it and what to do next, and implement it carefully, and apply the knowledge in the book to your life. If there is no "next plan" and specific actions, then the book you read will stay in the reading stage. At the same time, you should set yourself goals, such as the plan after three months, and look back after three months to see if you have achieved it (track and record your reading and action results).
If you want to make it more detailed, you can organize the books in the form of knowledge framework or mind map, mainly to extract the important contents of the books, including some understanding and feelings you have in the reading process (if you have relevant new knowledge points and new experiences in later study or reading, you can also supplement them and establish knowledge links to facilitate mastery and application). You can try to write about your feelings after reading it.
The efficiency of reading and the harvest of reading are directly related to your reading method.
In order to improve the efficiency and harvest of reading, you can try my method: when reading, first read the basic information such as preface and table of contents, and then ask a few questions according to these basic information and the purpose of reading this book, and "answer" my questions with some knowledge I have. Then read the whole book or some chapters at a speed of about 2000 words per minute (mastered by Elite Speed Reading), thus establishing the context and knowledge structure of the book. During this period, I will find places that I am interested in, places that are important to me, or places that I don't understand, and then mark these contents simply and quickly. If necessary, these contents will be read twice and intensively. After reading this book, answer the questions raised before reading it again "according to the content of the book". After the answer, compare the answers before reading and after reading to see how many of your answers are the same as what the author said, and what are the omissions and gaps, and then pay special attention to these omissions, gaps and differences.
This way of reading is very troublesome at first glance. In fact, this not only saves time, but also improves your reading gain, because it can exercise your reading comprehension, analysis and integration ability and thinking ability.
