Is it better for children to learn one craft or to master all 18 martial arts?

I think if you really have that kind of energy and intelligence, you will definitely be better at mastering all the eighteen martial arts, but in fact, it is difficult for most people to master one craft, so it is basically impossible to master the craft of 18, so you must be very proficient in one craft before you can touch other things. If you always touch each craft shallowly, you want to touch another mobile phone. Let me give you an example to explain why it is better to master a craft.

My nephew was actually interested in playing football when he was young, but my sister wanted him to develop in an all-round way, so she signed up for piano classes, swimming classes and taekwondo. He plays the piano very seriously, but after all, piano is not his interest, so he has never played very well. Later, he learned Taekwondo well, but he failed to persist in swimming in the end, especially so. Because his sister enrolled him in too many courses, he only learned a little in each course, which led to him not really mastering one thing, so it was not so good for him. If my sister only enrolled him in one class and he was interested, I think he would study this course very hard, which is good. So I think we should focus on mastering a craft first, not eighteen, because mastering so many things actually takes a lot of effort and may not be possible. So we must work hard first, and then work hard.

To sum up, this is why I think we should do a good job in one craft before learning another. Only in this way can your heart learn this craft more professionally.
