Structure & Surprise 
Vonnegut is such an adorable rascal. I’ve learned so much from reading his novels. And what an interesting video on his approach to stories. I’ve written and sold a few short stories, but I’m primarily a poet, and suspect some of his ideas about structure might also apply to poetry, which can also tell a story if that is the poet’s intention..
Absolutely applicable!
