On what advice he would give himself if he could go back to the start of Supernatural and do it all again:
"Get more sleep. Get more rest. Figure out a way to pace yourself early on because those first several years were just exhausting. When we came back after the writers’ strike I had realized that I’m gonna need to like find a way to pace myself a little better because I was just exhausting myself. And I have. I feel like I even got better because I really kind of sat down and thought about my work ethic, and how I was gonna approach certain things."
