Look at this place! Personally, if you go to school, look at the atmosphere. If many people learn guitar, the atmosphere of learning guitar is very good! If you start your own training institution, you can see where it is. It is usually difficult at first, especially for publicity. But you can add other businesses on the basis of training, such as selling guitar accessories, especially guitars, which I have done before. That's very profitable, really. So, hehe, come on! If you want to do it, I think it's not difficult for you!
