I am a junior college student majoring in tourism, but I like broadcasting very much. I don't know if I can do this industry in the future. I want to teach myself. Is there any way or good way?

You can do it if you want to. You're afraid you won't succeed if you don't do it. The way is to learn from the predecessors who are now broadcasting, and you can check the information and podcast articles of those who are now broadcasting on the Internet. The way of self-study should also ask these broadcasters. A good way is to study broadcasting hard. It mainly depends on whether you have the conditions for broadcasting, such as basic Mandarin, physical condition and appearance condition. If you don't have the basic conditions, you'd better not change careers.
