He discusses the difference between reading for content and actively reading for writing choices and techniques made by the author to better your own writing. Bunn writes, "Questioning why the author made certain decisions. Considering what techniques could have made the text better. Deciding how to include the best attributes of what you read in your own writing. This is what Reading like a Writer is all about."
