it's good to have hobbies, and people with hobbies are more cheerful.

Subjects that are too difficult are good opportunities for you. In the future, when you enter a university or step into the society, you will understand that when you study and challenge these difficult subjects, you not only learn the knowledge of mathematics and English, but also learn how to study and how to deal with such a difficult situation. This is an ability. If you persist now, you will appreciate your persistence now in the future.

I hope you can achieve more goals and make better progress.
