Writing dialogue is putting down conversations that characters have with each other. It doesn't feel any more 'talent-dependent' than going to a chicken farm with the hope of buying eggs and -- by the gods, what is this?? They have eggs for sale!
Without some context, I have no way of knowing if I'm any good at something. It feels more like a warm mess of good fortune simply fell into my lap.
