To be completely honest, I'm not really sure I believe in this idea of talent. IMHO, anyone without some kind of mental impairment who's determined enough is capable of being a great writer.
There are times where I feel like people cripple themselves by thinking of talent as this nebulous, mystic thing that they either have or don't, instead of a hell of a lot of smaller skills/techniques that can be observed, broken down and absorbed.
Again, IMHO, talented people are just those who got a head start by figuring out a lot of that stuff growing up... like kids who had readers for parents or those who loved escaping into books (and the techniques they saw happened to stick), etc.
If that's true, about ninety-nine out of a hundred new writers I've had experience with are doing something unbelievably wrong. How do you explain all the writers, and I think ninety-nine out of a hundred is generous, who work as hard as it's possible to work, who have been readers since childhood, who study writing, who take classes, and who write dozen and dozens of short stories, or a dozen novels, but never do write anything that even remotely professional level?
Who know, maybe picking up techniques and having them stick from what you read is talent, but if so, a lot of writers lack the ability to do so.
Anyone can learn how to write, and how to tell a story, but if you read slush piles for a couple of decades, you'll learn very, very, very few can learn to do these things at a professional level. You see the same names year after year after year, and often decade after decade, and with no improvement.
I've known quite a few of these writers, and all most all of them had parents who read, almost all of them love to read, and always have. Almost all of them have done everything possible to become good writers, but it simply is not going to happen. Ever. Whethe ryu call it talent or not, they lack teh ability to write well enough, to tell a story well enough, to do anything well enough, to be good writers, let alone greats ones, and there simply isn't anything they've done that they shouldn't do, and anything they haven't done that they should have.
Not everyone can do everything equally well. They just can't. Writing is no different. Maybe a writer doesn't need much talent, and hard work certainly matters, but no one can possibly work harder than many of these writers who simply never write anything worth reading.
Likewise, I've seen a lot of writer who did not work hard, who did not study, who probably read a good bit, but who have done nothing else, just sit down one day and write something that's as good as anything, anywhere, be it an amazing short story that sells to a top magazine, or a novel that becomes an almost instant bestseller.
Talent exists in every field. You may not need a lot to be a writer, but you need some, and not everyone has it.
Hard work is a great thing, but all the hard work in the world can't turn someone without talent into a great writer, or a great anything in any field.
