It's good not only to realize that you can't please all of the people all of the time, but that you don't want to. There's a certain type of reader that you don't ever want to write for.
“The only thing that exists is torment, lyricism, and the magnificence of language.”
“You have to write the book that wants to be written. And if the book will be too difficult for grown-ups, then you write it for children.”
