I think that Stephen King is a good author-ly voice to heed. He certainly knows how it’s done–he can buy all the groceries he wants, now! In fact, I think he’s hit the nail on the head. The nail is the problem, of course. And King might have been defining success, but I believe he’s actually defining the issue many aspiring “writers” face: bein’ considered legit. Street credit, if you follow.
And now we live in a world where everyone is vying for your attention, we’re bombarded by stimuli, and I wouldn’t be surprised if there’s a literary reaction to this. Not that it would get anyone’s attention, it might just die in a corner somewhere.
