The first is to determine the reading goal. Before reading, I want to know why I want to read this book and what my goal is, such as answering a question and finding a way. Only by reading with a goal can you know where you want to underline and mark.
The second is to determine a set of signs that belong to you. That is to say, different colors of pens, labels and symbols are given a fixed meaning. For example, use green to represent the important content related to your work, use red to represent new knowledge and new ideas, use blue to represent good words and sentences, use circles to represent names, and use boxes to represent place names. For your own thoughts and feelings, you can write them in the corresponding position on the page, or you can write them in your notes (notes with different colors also have fixed meanings), and then paste them in the corresponding position. After this habit is formed, we can find what we need quickly and clearly when reading books, taking notes and looking for information.
The third is to index. It is to write down all kinds of marks you have made on the title page or blank space of the book, and then write down the page number corresponding to the important knowledge after the corresponding marks. With the index, once you need to use the relevant content in the book in the future, you can find it quickly.
In the process of reading, annotation and annotation are only a small part, and the key is to master the appropriate reading methods.
First of all, you should study with questions and goals. The reason why I don't have much impression after reading it is because I am blind when reading, and there is no problem in my mind and no clear purpose. Pay attention to a problem and a goal when reading. When you pay attention, you will naturally jump out, grab your eye and enter your mind. If the book is good, when you are going to read it again and again, you should pay attention to finding a separate target every time you read it. So what you see will be different.
Secondly, we should know how to read quickly. For most books, the important content only accounts for about 20% of the whole book, so we should change the reading habits and methods word by word and learn to read through fast reading. I usually read at a speed of about 2000 words per minute after learning to "speed read". In the process of reading, I find places of interest, places that are important to me and places that I don't understand. Then I slowed down and read the essence I found in my reading again.
Take some notes after reading it. More fundamentally, after reading a book, actively guide yourself to recall and think, such as asking yourself: What is the main content of this book? This class focuses on several important knowledge points. What have I learned from this book? What knowledge is there in the book that I have never heard of? How does this book help me? What problems can this theory or method be used to solve, how to do it, and so on. In order to better understand and remember the contents of the book, you can learn to split, reorganize, integrate and extend the contents according to your own actual understanding, and take reading notes.
