I studied neuroscience at the cellular level, so I was looking at learning and memory in the visual cortex of rats. Neuroscience mainly exposed me to a way of thinking - about experimentation, about what you believe to be true and how you could prove it - and how to approach things in a methodical manner.

Most of us yearn for really intimate, healthy, in-person relationships. People have a deep desire to be understood, to be told that it's OK, that you're not isolated and broken, that this is part of the human challenge, and that there is hope. The capacity for online interactions to do that is powerful.

Let me think about the people who I care about the most, and how when they fail or disappoint me... I still love them, I still give them chances, and I still see the best in them. Let me extend that generosity to myself.

On street corners everywhere, people are looking at their cell phones, and it's easy to dismiss this as some sort of bad trend in human culture. But the truth is life is being lived there. When they smile - right, you've seen people stop - all of a sudden, life is being lived there, somewhere up in that weird, dense network.

Facebook has woven itself into the fabric of our lives and the foundation of the Internet. I think everything will be redefined because people are using their real identities on the Internet.

I think it's great when people accuse me, almost always falsely, of promoting conspiracy theories, because that shows how effective I am at messaging and how effectively I can use social media.

People don't change very much, and the things life ends up being about don't change from generation to generation. Life is about love. And people's stories don't really change. Your environment changes dramatically, technology changes, but people don't change, in the way our minds work.

I'm not comfortable being around too many people. I don't like being out in public too much. I don't like going to bars. I don't like doing celebrity stuff. So most of the characters I play are people who don't always feel comfortable beyond their small circle of friends.
