Making choices when writing

Yesterday’s post made me think of this great scene between Michael Douglas and Katie Holmes’ characters in the movie Wonder Boys:

Hannah Green: Grady, you know how in class you’re always telling us that writers make choices?
Grady Tripp: Yeah.
Hannah Green: And even though you’re book is really beautiful, I mean, amazingly beautiful, it’s… it’s at times… it’s… very detailed. You know, with the genealogies of everyone’s horses, and the dental records, and so on. And… I could be wrong, but it sort of reads in places like you didn’t make any choices. At all.
