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.

If a man made himself an expert in any particular branch of human activity, there would result the strong tendency that a peculiar aptitude towards the same branch would be found among some of his descendants.
