I read this book back in high school, which already suggests that I knew what I liked already I just didn't know how to go for it. But anyway, I remember liking it. Here's the description:
Becoming a Writer recaptures the excitement of Dorothea Brande's creative writing classroom of the 1920s. Decades before brain research "discovered" the role of the right and left brain in all human endeavor, Dorothea Brande was teaching students how to see again, how to hold their minds still, and how to call forth the inner writer.
