Riding my motorcycle around L.A. is like my own video game. But unlike many folks at the wheel, I am occupied with getting where I'm going and keeping myself safe. Most people are applying makeup, texting, and checking out the beauty in the next car.

I was shown into a room. A red room. Red wallpaper, red curtains, red carpet. They said it was a sitting-room, but I don’t know why they’d decided to confine its purpose just to sitting. Obviously, sitting was one of the things you could do in a room this size; but you could also stage operas, hold cycling races, and have an absolutely cracking game of frisbee, all at the same time, without having to move any of the furniture. It could rain in a room this big.

Celebrity is absolutely preposterous. Entertainment seems to be inflating. It used to be the punctuation to your life, a film or a novel or a play, a way of celebrating a good week or month. Now it feels as if it's all punctuation.

Driving a motorcycle is like flying. All your senses are alive. Being House is like flying, too. He's free of the gravity of what people think.

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.

People assume that I'm very highly trained, that I studied and did years and years of Shakespeare. I have no training whatsoever and I've only done one Shakespeare play at university. If people want to believe that, I'm happy to go along with it.

They, all of them, work incredibly hard to make me seem clever and heroic, neither of which I am.
