First, get in touch with books and pick them up. Only by more contact can we love it and have enthusiasm for it. You don't have the enthusiasm for reading now, probably because you are busy with work or study now, so you can spend half an hour, fifteen minutes or even five minutes reading books every day. Maybe slowly, you will get more books, your interest will increase, and your enthusiasm for reading may come back.
If you don't have the enthusiasm for reading now, there is probably another reason: there are not many people around you who read. Influenced by the people around you, your attention to books will be reduced, your reading time will be reduced, and your enthusiasm for reading will gradually decrease. If you want to regain your enthusiasm for reading, on the one hand, you should consciously regain your reading of books and sentences, on the other hand, you should also drive your friends and colleagues around you to read together.
When there are more and more people reading around you, you will pay more attention to reading and have more time and opportunities to study. And if you are surrounded by people who love reading, the topics you discuss are likely to be related to books, which can also promote your reading and improve your reading enthusiasm.
