With Every Mistake is a collection of Gwynne Dyer's articles published between September 11, 2001 and the Iraqi election in 2005. The articles are interspersed with commentary from Dyer which includes discussion of the issues, reflections on the Canadian publishing environment, and self-criticism for the things that he got wrong. The title is taken from the Beatles' song, "While My Guitar Gently Weeps", by George Harrison: "With every mistake, we must surely be learning."
