My study habits are like this:
Not to mention reading professional books. After all, it is the need of work, and the serious place must be very serious. Tell me about books about hobbies.
The first is to choose books. Most of the books I read are not recommended by others, but what I need in my heart. For example, I suddenly want to read a popular science book about economics, so I choose the one in economics. If someone recommends a novel at this time, even if it is excellent, I will not go back to read it.
Secondly, I read books. After I got the book, I looked at the catalogue first. I like to read specific words carefully. I read them more than twice. Even read it word for word the first time, and deeply understand its content or style the second time.
For example, when I read Huang Renyu's Fifteen Years of Wanli, the first time I read the content word by word, the second time I will know the essence of Ming history and the author's mentality. Maybe I will mark the new words I don't know for the first time (there are many new words in history books).
Finally, the collection of books has something to do with buying books. When I buy books, I pay more attention to the publishing house and cover style. For this kind of books that I am satisfied with (in fact, I have never bought anything that I am not satisfied with), I will never cover them. Even if it is old, I can see the history of this book and remember when I read it. I don't like dust on books. I hope to have a sealed medium-sized bookshelf.
