A good way to read is to read a chapter every day. If one chapter is not enough, read another chapter. Many a mickle makes a mickle, form a habit. Especially for big books, you can read about 500 pages in about three weeks by this method. If you read slowly at first, you can read less first, read a chapter every two days, and then slowly increase the amount after reading quickly. If you persist in this way for a period of time, you will find a book that you have never read before, and now you can finish it soon.
If we want to absorb the contents of the book, we must learn to read intensively. We should have a cognition that a book should not be regarded as a "book", but as several "chapters". Grasp the structure of a book quickly from the perspective of "chapter" The more you look at the structure, the more you can master the system of knowledge. Many classic works are abstruse and difficult to understand. Read them slowly and word for word. The purpose of reading these works is to open your cognition, not to cater to your existing views. So don't treat the books you want to read in the way of "reading on demand" such as "reading only what you want to read" or "reading only what you need". When you get a new book, you'd better browse it first and read it through to get a general understanding, but then you must read it intensively.
If you want to have a more enjoyable reading experience, you should take the initiative to break the restrictions imposed on yourself in the past, let go of the burden of "reading must be rewarded" and "reading every detail", and subjectively regard reading as a way of entertainment in your leisure time, a way to understand the author's views or imagination, rather than adding new tasks to yourself after work and study.
