let me quote a comment of myself about this topic:
"well its really the same thing for everything. you can learn everything if you put your heart to it no matter how "not gifted" you are. but a very key component to this is to know how to actually become better at something, and many people dont realize that. they TRY to get out of bronze buit they cant because they actually never made the conscious experience of how they got better at something. if you just do something and keep trying, sure you will get better eventually like a baby trying to stand up and walk, but you will not become extraordinarily good unless you understand the concept of learning, making progress.
this means, even tho in theory everyone can become good at something, not everyone actually will, even if they put in years and years of training and effort.
"talent" in that sense is the way your brain has coincidentally learned to work. some people are talented in music, some in art, some in strategic and logic thinking i.e. warfare/war games like league of legends, poker and starcraft.
this comes from our brain finding a way to comprehend things during our infant stages, even embryos. depending on how your brain learns to comprehend the world around you, you are more "talented" for something, but not because its a gift, but because you actually spent time training your brain how to do this certain act of thinking.
now some great musician might try to become challenger in league and he just doesnt fucking do it ever. its impossible for him, he doesnt understand why. he trains so much and he just cant figure out how to carry bronze games. now if he wants to learn the game, he has to not actually learn the game first, he has to learn how to think and analyze logically and strategically. he has to understand how his brain works and how he can teach himself to learn different ways.
but since this is very hard to find out yourself and not everybody will stumble upon this lesson, its a simple fact that none of you will ever reach challenger because you simply cant. doesnt have to mean you are bad, but still does."
