From the utilitarian point of view, it seems that modern society does not need calligraphy, but in fact, the rarer it is, the more precious it is. I don't know that the giant panda has become a national protected animal and the ancient city of Pingyao has become a world cultural heritage. Therefore, calligraphy will receive more attention in the future and will be pushed to the height of saving China culture by people of insight.
In addition, non-utilitarian, calligraphy is also a good choice for individuals to "cultivate self-cultivation", which can improve their artistic appreciation ability.
So, you have to stick to it. It takes a lot of resistance to realize your dream, including your confusion.
