Learning anything is useful. Learning itself is a kind of exercise. It would be great if what you learn happens to be what you are interested in.
Any talent can cultivate one's temperament and character. People who study a certain musical instrument for a long time have different temperament from others.
Moreover, it is said that learning musical instruments can open up one's own brain domain, and the human brain is really utilized less than 10%. The learning process itself is a process of developing the brain.
Whether learning dance or music, or learning calligraphy and painting, each has its own strengths, and art is interlinked in the final realm.
So when we learn one thing on the level of Tao, we will find that everything in the world is similar on the level of Tao, and it will be easy to learn one thing and then another.
We will find many cross-border talents, not because they are really smart, but because they have learned something to the extreme, so for some similar disciplines or even some completely different disciplines, they learn science much faster than ordinary people.
The human brain is like a net. Open them one by one, and they will be connected into one piece and then into a large piece.
When there are more and more interconnected areas, the part of the brain that is used and exercised becomes bigger and bigger, and people will become smarter and smarter.
So don't worry about how much money you can earn by learning a talent. Learning itself is useful.
