I would just hear piano players and I would hear music, and just think - I don't just want to sit here and passively listen; I want to get inside it.

I would cling to unhappiness because it was a known, familiar state. When I was happier, it was because I knew I was on my way back to misery. I've never been convinced that happiness is the object of the game. I'm wary of happiness.

I have been instrumental in banning bottled water on the set. It hasn't gone that well with the crew... so I replaced it with tequila.

I'm finding it increasingly difficult to simply walk down the street. In New York, I dashed in to buy a big pair of sunglasses to conceal myself, but the guy behind the counter shouted 'Hey! It's Dr. House.'

When school friends would think about appearing on stage as the most frightening, the most awful, intimidating experience ever, I knew that it was something I could do.

It gets on top of me and I get frustrated.

To tell you the truth, the older I get, the less I know. I keep meeting people, both older and younger, who seem to have accrued so much more knowledge or expertise or certainty about who they are and the jobs they do. I just marvel at it.
