How many people who believe you can't be taught something actually enroll for classes? Surely the action contradicts what the mouth says?
Re: the idea that some comedians have a gift of timing. When we see them on TV we see the finished product that came about after countlessly getting it wrong, and of learning from their mistakes how to finally get it right. So to me, that's an ability to learn from mistakes not an enigmatic talent handed to them before they even spoke their first joke and screwed it up.
The idea of being a born-this or -that is a retrospective tag. It is a nonsense because it is only applied to those that succeed, not to the countless others who tried and failed. Few people here would dare apply that tag (born-writer) to themselves now but if they went on to greater things then they'll undoubtedly be described as born-writer. Nothing about that person has changed, but the success confers the title.
The point with a mystical god-given gift is that it can be seen to be elitist. For example, many famous writers say that they were persistent and worked hard and that anyone can achieve what they did but then slip in the sucker punch of the gift. Why? To seperate themselves from the masses of wannabes.
If anyone here seriously believes writing is primarily a gift and they persist in writing then they must believe they possess this quality. If I believed in such a notion and felt I didn't have the gift then I'd give up. There'd be no point fighting destiny.
Hard work, perseverance, an ability to self-edit, to analyse your mistakes, to meet deadlines, to write when the inspiration is thin, to be consistent, to write to someone else's brief, and to improve on past performance are all qualities that will push a writer forward. But no amount of 'natural talent' will allow a person to succeed if he doesn't combine it with other prerequisites.
Also commercial and critical success is no guideline to talent. We all know of many talentless and mediocre writers who succeeded. They probably constitute the bulk of success stories and a few are mega-successful. They certainly haven't got a gift, so it seems clear that talent is not only just one factor that makes a successful career but that it isn't even the most important factor.
