Let this sink in: in the time since Rothfuss first published The Name of the Wind (the first book in a trilogy that was already written, he claimed), Brandon Sanderson has published 41 novels, short stories, graphic novels, and collections. The Way of Kong's didn't publish until 2010, and he is already expecting to publish book 4 next year.
What has Rothfuss published since then? One novel, a handful of short stories/graphic novels, and about a thousand blog posts about how he can't write because Trump got elected.
