I wonder what I need to learn if I want to be Art editor.

Learning comes first. Now which enterprise doesn't attach importance to diplomas?

I can tell you responsibly that you study art instead of studying. Even if you have achievements, you are only an artist.

You need a lot of knowledge to be an American editor. An editor may not have much knowledge, but he must have a wide range of knowledge. For example, Art editor didn't just paint for a beautiful editor of a book. You have to grasp the content of the book and design according to the content and connotation of the book. Don't design scary covers for children's books.

Whether you are an American editor or not, you must have knowledge. Now that you are a high school student, it is even more undesirable to give up the idea of studying. Being an American editor requires a lot of professional knowledge, editing principles and so on.

As for learning, what's not to look at academic qualifications now? Becoming a monk requires a bachelor's degree. After joining the work, the requirements of some positions are academic qualifications. If you are not famous, but you have no education, who will take you there?

I am a university editor and publisher. I suggest you don't fall behind in your studies. Otherwise, there is basically no future for making an American editor unless you are a genius.
