Mainly I thought of Barney as a kid. You can always look into the faces of kids and see what they're thinking if they're happy or sad. That's what I tried to do with Barney.
I think when you begin to think of yourself as having achieved something then there's nothing left for you to work towards. I want to believe that there is a mountain so high that I will spend my entire life striving to reach the top of it.
