I wasn't born with an uncanny writing talent, I was thought to be retarded but I liked telling stories. So I spent a lot of my childhood from 13 years old, when I realized that I wanted to write books for a living, practicing writing. I read huge amounts of books to learn how different people write and taught myself.
At 17 (I'm from the UK I graduated at 16) the editor was telling me I was the most talented writer they had. I surprised him one day, he sent me an email at around 6 saying one review I did wasn't how they wanted it (which was the reason I left, the product I reviewed sucked ass but because it came from a big company we couldn't offend them) so he said it needed changing. An hour later I emailed him back with the entire thing rewritten the score from a 1 to a 8. For everyone who doesn't know the review game; for example a video game review, if it takes 10 hours to play the game it will probably take you around 20 hours to review and edit it, so getting an essentially new review in an hour was amazing to him.
The reason why I could do a review in an hour that would take anyone else a day to get back. Well because I'm driven. I'm sure there were more talented people on the staff, but that doesn't mean shit when I can consistently out perform someone 10:1.
So yes being talented will help you, but if you're a slacker you're not going anywhere to begin with.
