I’ve heard Patrick Rothfuss speak at events in person twice since he released the second book of the Kingkiller trilogy in 2011. Both times an audience member asked him how to deal with writer’s block, and he responded “You don’t get to have Plumber’s Block. If your job is to write, you write.” The third book is still not written enough for him to release a chapter of it like he promised as part of his kickstarter stretch goal five years back.
I guess what I’m saying is admitting to writer’s block and not finishing a book don’t always go hand in hand.
