"At the risk of overgeneralizing, the most important talent is meta-analysis. You have to be able to self-analyze and self-correct." I disagree with the OP but this I can get behind. I teach at the college level, and I have seen, repeatedly, students who put in a lot of effort but get nowhere. Not a ton, but always a few each year. There's also almost always a much larger group that maybe muddle along to a passing grade but don't understand why they don't understand more. What both groups have in common is an inability to learn from their own errors. They can listen to what I say, and absorb some of it, and they can read the book, and absorb some of it, and after they've gotten something wrong they can come back, talk to me or a tutor, and absorb a little more. (Maybe.) But the more productive route by far is to look at the specific thing they got wrong, and learn from that, "fix" the specific misunderstanding that misled them. And whether by inclination or ability, they don't do that. And despite spending big chunks of time on my class, they don't do very well. I do think there is such a thing as native talent. There pretty much has to be. But I think that the skill of meta-analysis can account for a large percentage (not all) of what is usually chalked up to "talent".
