I've encountered several variations on a quote claiming that typically an author would need to write either a million or half a million words before becoming proficient as a writer. I've heard, too, that it takes about that for most authors to find their Voice. What I haven't been able to find is who quote originated from. I've read that it could have been Ray Bradbury or David Eddings. Does anyone know for sure?
Karen Woodwards researched this very quote in a blog. Here is the link.
