Just like I like to keep running, not just for exercise. It can improve physical fitness, relieve stress and improve attention. Suddenly I don't want to study, but I can't see anything. When I am unhappy, I will come back to exercise immediately. A hearty long-distance running. People are very tired when they run down. But suddenly I lost my clarity. It's too tiring to study, so it's better to stop and relax your brain.
I like reading early, and I have the most energy in the morning. It is quiet in the morning because it is the most active. Reading quietly with a book in front of the table, I feel very focused. I can't concentrate on reading in the afternoon and evening. Therefore, it is more difficult to keep getting up early. Then you form a habit, and you will find that reading is a very active thing. You'll still be addicted.
