Enhance self-control, divert attention, listen to music and do exercises.
Enhance self-control ability. Part of the reason why we are obsessed with novels and cannot quit is because we have insufficient self-control and cannot control our own behavior, control our own thoughts, and divert our attention. When we want to read a novel, we must learn to divert our attention. We can study or read some information about studying, and try to keep ourselves busy, listen to music and do exercise. When we have time to read novels, we can find friends to exercise, or listen to music and fall asleep by ourselves to quit reading novels.
When you are really addicted to novels, please bring your own pen and paper and write your own novel to satisfy your craving. But be sure to find new novels to read, or you will easily fall into it again. You can try to develop other hobbies, such as playing badminton, which will divert your attention.
