the value of digressions

Just ran across Sarah M. Broom's essay in The Paris Review about the long process of writing her book The Yellow Room. Loved this:  "The unfinished work is no less real, or necessary, or powerful than the book. How we need it, this work, these long, beautiful digressions, these surprises. May we continue to gift writers with the time for wildness. May they ramble, digress, go beyond the edges of all the known and touted maps, may they hew close to the question, to unearth the questions beyond."
