A Million Miles in a Thousand Years: What I Learned While Editing My Life (2009) is the sixth book by American autobiographer Donald Miller.

It centers on the realizations that Miller came to while editing his critically and financially successful memoir Blue Like Jazz into a screenplay for a movie, directed by Steve Taylor.

Miller is shown transitioning from sleeping all day to riding his bike across America, from living in romantic daydreams to experiencing fearful encounters with love, from wasting his money to founding a non-profit with a passionate cause.

A review on Publishers Weekly concluded that audiences who enjoyed Blue Like Jazz would "find here a somewhat more mature Miller, still funny as hell but more concerned about making a difference in the world.

"[2] This sentiment was expressed by Denver Journal, whose critic agreed that when "Miller sets out to explore the implications and effects of [living a better narrative]," this "extended reflection on life as a story showcases a somewhat more mature Miller than that of his past books, although A Million Miles does retain much of his characteristic light and informal style."
