I don't really try to judge any character that I play, afterwards I figure it out, but while I'm working on the character, I have to find something in them to relate to.
Sometimes you can't see yourself clearly until you see yourself through the eyes of others.
When you're a carpenter making a beautiful chest of drawers, you're not going to use a piece of plywood on the back, even though it faces the wall and nobody will ever see it. You'll know it's there, so you're going to use a beautiful piece of wood on the back.
