I've been a professional writer for over a decade and it still amazes me how many folks are CONVINCED they can just do this shit. Nobody walks up to a surgeon and says "I reckon I could have a crack at that." But writing? Everyone's got a world-changing essay in them apparently. It's in there. Somewhere. Behind the spleen.
@Daojoan But you are, simply, a great writer. So a comparison is tricky.
Talent, experience and hard work is in there. And like a physical athlete, the talent comes out when the hard work forms the experience.
And people who think they can do your thing right out of the gate should fuck off.
