The first is psychological preparation. Be clear before reading, what is the purpose of reading this book? What will you get from it? If it is a novel, your purpose may be to understand the plot and characters. If it is a book of humanities and social sciences, your purpose may be to memorize the knowledge points of intensive reading. If it is a book with practical skills, such as thinking methods, your purpose is to grasp the logical context of the author and absorb it into the knowledge system.
Then there is psychological preparation. You need a relatively quiet environment, get rid of distractions and concentrate. If this is difficult for you, I recommend you to use the orange consciousness method. The orange consciousness method is to focus on the oblique upper part of the back of the head, imagine a point where consciousness gathers, and then imagine putting an orange there to keep balance. It may be uncomfortable at first, but after a long time, you will form a conditioned reflex.
Second, the reading stage.
First, browse the catalogue and get a general idea of the overall framework of the book. Find out the key parts you want to focus on in reading, and you can focus on it in reading.
When reading, you should use your eyes and brain to cooperate, and don't read by sound. Pronunciation is inefficient. Pay attention to capture keywords when scanning eyes, and you can sketch keywords directly. I suggest that I create a set of habitual symbols. Let me introduce mine: if the logical relationship is parallel and the book is not numbered, I will label myself with numbers to form several points. From 123 to 123 to (1)(2)(3), proper nouns are enclosed in square brackets, and noun explanations are enclosed in ordinary brackets. Underline the key sentences and use wavy lines if you need to extract them.
Third, the closing stage.
After reading it, we should comb it again with the catalogue and consolidate it in time, because there are scattered pieces of information in our minds that need to be put in different drawers in our brains.
It's best to draw a mind map and straighten out the key points. If not, you can comb the frame according to the symbol structure.
