Take art and studios for example. In fact, the most important thing is your own comprehension ability. I have seen a lot in the studio before and studied for several years. Studying for a few months is not as good as a person with strong comprehension ability, so the most important thing is yourself.
If the understanding ability is poor, it can be improved by drawing more, practicing more and copying more.
If you have a strong understanding, draw more, practice more and see more. Read more and understand.
Anyway, I personally think that no matter what kind of art students and training bases are good, they can only say that they account for 20% and 80% are on their own!
I hope it helps you!
