So every night I read to @roycedaniel what I wrote that day, and he gives me feedback, and then we have these long conversations, on what to improve, etc, etc. Tonight I read to him two chapters and when I was finished I waited and waited for him to say something and he was just quiet.
"Feedback?" I asked.
He looked at me and said, "That made me hard."
This was the best and the shortest and the most succinct feedback on my writing I ever got from him. Four words.
