It's not difficult to take care of a child; it's difficult to do anything else while taking care of a child. Trying to clean up the kitchen after you've had a baby is a nightmare because you have to wait for the baby to be asleep, you're exhausted, and you really don't want to clean up the kitchen now.
Behavior is mutable. It changes from place to place. It's like accents, dialect - it varies from one area to another. But there are universal truths about what it means to be a human being. All the other stuff is like applique. Learning that was interesting to me and probably useful for becoming an actor.
I actually think acting is a form of self-hypnosis. You have to be hyper, hyper aware of what's going on around you. You have to know where the lens is, what the shot is, and where you're moving. And then you have to trick yourself into an emotional state where you believe this stuff is actually happening.
I moved frequently because my dad was in the army, so I was always new in school. I think if you've ever done that, you know what it means to not matter in a room. I think it's a good experience for everyone to have, to feel like they're not noticed, because it teaches you to be empathetic.
