Many people are suffering from anxiety and pain because they focus on the superficial amount of learning. They have read many books, signed up for many courses, checked in every day, persisted every day, and worked hard to move themselves, but they have never deeply focused on their own thinking, actions, and changes. Therefore, they always feel that they have gained nothing from learning, and even think that they are not working hard enough, and they should increase the amount of learning. As a result, they fall into a vicious cycle of "the more they learn, the more anxious they become, and the more anxious they become, the more they learn."
