Without practical experience, people often indulge in theoretical knowledge and subjectively participate in internships according to their own imagination, which makes it difficult to achieve the expected results. The countermeasure is to open your eyes, put yourself in the position of primary school students in the internship, face new things, learn while doing, experience the theoretical knowledge you have mastered in the study, and do everything including "some trivial things" in a down-to-earth manner. Stick to it and you will grow and reach the height you want.
