Is this maybe a western cultural bias, that somehow God blesses you with talent and that's it? Some residue from aristocracy?
When you look at things like Japanese martial arts, it's all about learning from someone more experienced and lots of hard work. The limiting factor is your endurance, and the general sentiment is that "if someone learned before me, I can too".
I'm not sure about that specific instance of Japanese culture, but for East Asia I'd say fixed mindset was much more relevant. I grew up being told that I will never do anything great with my life (not in a mean you-are-stupid way, but just a seemingly "rational"/"realistic" world view that only a few very smart people can do great thing, and I'm not one of them).
