Mark Ruffalo

I was an introverted kid; I liked my time alone. And the rest of my family is pretty extroverted, so I felt like a bit of an oddball. They're very gregarious and charming and charismatic people. I always felt like I was struggling as a young person. I think everyone was very surprised to hear that I wanted to be an actor.

I routinely oscillate between exultation and despair. Maybe at the end of the day I feel pretty good about what I've written, but the next morning I see that it's crap. Then I start again - make a new outline, do some more research, try to rethink the whole question.
