Why is it awkward to study for a long time?

Haha, I have the same problem. I don't need to read to talk to people. Sometimes I am always laughed at by my friends. You should read for a long time, because your tongue will be paralyzed and tired. Why don't people who usually talk a lot do this? I think the tongue after exercise is as flexible and powerful as other parts of the body. Usually consciously read more books, talk more, pay attention to make your pronunciation clear and powerful, and your eloquence will naturally make great progress.
