I often think about this question, because i often think i don't.
As one commenter stated, talent comes in two forms - writing and storytelling. Perhaps i can string some words together but can i keep an audience captivated? I honestly don't know.
So, i came across this comment which really struck me, (so much so i'm posting it here)
Definitely something i need to keep reminding myself!
"I have no idea whether I have talent or not. I have no idea if I'll be published or not. Since these are things I cannot control (well, not completely anyway), I've decided not to worry about them anymore.
Instead I'm going to write my first book and see how it turns out. Then I'll write a second book and see how it turns out. Hopefully more (and better) books will follow.
When I have a novel that I feel is publishable, I'll polish it up as much as possible and send it out into the world and see how it fares"
