I run six-to-eight miles a day, plus weights and aerobics in the lunch hour. I also lie a lot, which keeps me thin.

To be able to pretend to be something that I'm frankly not is very liberating and exciting.

I couldn't imagine what Fox thought they were doing, contemplating such a jagged protagonist for a prime-time drama. I only knew that I wanted the role very much.

I never was someone who was at ease with happiness.

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.'

I feel like I'm working on an oil rig right now. I'm away from home a lot.

Driving a motorcycle is like flying. All your senses are alive. When I ride through Beverly Hills in the early morning, and all the sprinklers have turned off, the scents that wash over me are just heavenly. Being House is like flying, too. You're free of the gravity of what people think.

I didn't realize House would be the central character, more the bitter comic relief appearing occasionally. I relish his wounded nature - the lameness, the scarred Byronic hero.

As a real person, he wouldn't last a minute, would he? But drama is about imperfection. And we've moved away from the aspirational hero. We got tired of it, it was dull. If I was House's friend, I would hate it. How he so resolutely refuses to be happy or take the kind-hearted road. But we don't always like morally good people, do we?

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 have my moments. Ever since I was a boy, I never was someone who was at ease with happiness. Too often I embrace introspection and self-doubt. I wish I could embrace the good things.

My dad gave me my first bike at 16. I soon fell off and was in a wheelchair for weeks. I haven't fallen since.

I don't have a single complete show or movie or anything else that I could look at and say, "Nailed that one." But endless dissatisfaction is, I suppose, what gets us out of bed in the morning.

I run six-to-eight miles a day, plus weights and aerobics in the lunch hour. I also lie a lot, which keeps me thin.

Seems to me that this business, for actors anyway, is not so much about whether or not you do good work. It's about whether or not you get the chance to do good work.

I feel like a hostage to fortune. Not that I am complaining. I wanted to play the role. But in truth I didn't think the show would be such a success. OK, I thought it would fail. Not because it was bad. I was confident it was good, but plenty of good things just sort of wither on the vine.

I don't talk like House, or walk like him. I certainly don't think like him. I don't like to think for more than 15 minutes at a stretch actually; I am a fragile flower.

One of the principal goals in my life has been to avoid embarrassing my children by doing the job I do. I hope I've managed to do that, and I hope that, with the job I'm in now, they are, if not proud, at least unembarrassed by it. I must say, my three are most agreeable children, who do nothing but delight me.

Acting is largely about putting on masks, and music is about removing them.

Believe it or not, perhaps I don't show it much, or well, but I think I like people.

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.

Clive Dunn, as I understand it, retired to the south of Spain, where he worked extensively in watercolours. I don't own any of Clive Dunn's watercolours. I loved him in 'Dad's Army,' loved him. But not enough to actually seek out his watercolour work.

Directing is the best job going. I don't understand why everybody doesn't want to direct. It's an absolutely fascinating combination of skills required and puzzles set on every level - emotional and practical and technical. It calls up on such a wide variety of skills. I find it completely absorbing. I just love the whole process.

Even the greatest poets, I think, cannot quite get to the places that music can get to in the human - I was gonna say mind, but it's actually the entire body. It somehow seems to infuse the entire body.

Girls are complicated. The instruction manual that comes with girls is 800 pages, with chapters 14, 19, 26 and 32 missing, and it's badly translated, hard to figure out.

Humility was considered a great virtue in my family household. No show of complacency or self-satisfaction was ever tolerated. Patting yourself on the back was definitely not encouraged, and pleasure or pride would be punishable by death.

I admit I can't shake the idea that there is virtue in suffering, that there is a sort of psychic economy, whereby if you embrace success, happiness and comfort, these things have to be paid for.

I am a coffee fanatic. Once you go to proper coffee, you can't go back. You cannot go back.

I do actually like Los Angeles. Partly because I was told I wouldn't.

I don't have a single complete show or movie or anything else that I could look at and say, 'Nailed that one.' But endless dissatisfaction is, I suppose, what gets us out of bed in the morning.

I don't like the act of talking; it makes me slightly light-headed.

I don't really understand why everybody doesn't want to direct. It's an absolutely fascinating combination of skills required and puzzles set on every possible level, emotional and practical and technical. It calls upon such a wide variety of skills. I find it completely absorbing.

I don't think of myself as funny. I think of myself as rather grave, actually. And I'm suspicious of fun. I never quite know what that is or how to deal with it or how to generate it. That's my fault. I know it's a burden on the people I'm with. It's tiresome.

I feel when acting, I am sometimes overly self-conscious; I think, 'Going, no, don't, put your eyebrow back where it was and, you know, turn to the left.' You know, I'm sort of very consciously adopting this character. But with music, I don't know. I found it was a question of just closing my eyes and just sort of letting things come out.

I get anxious about a lot of things, that's the trouble. I get anxious about everything. I just can't stop thinking about things all the time. And here's the really destructive part - it's always retrospective. I waste time thinking of what I should have said or done.

I grew up with an impatience with the anti-scientific. So I'm a bit miffed with our current love affair with all things Eastern. If I sneeze on the set, 40 people hand me echinacea. But I'd no sooner take that than eat a pencil. Maybe that's why I took up boxing. It's my response to men in white pajamas feeling each other's chi.

I hate menus, I hate choosing food. I just want to be brought. Bring me dinner!

I have always stuck up for Western medicine. You can chew all the celery you want, but without antibiotics, three quarters of us would not be here.

I have resolved to pick one novel and just read it over and over again for the rest of my life, because I cannot remember anything anymore.

I just read an 800-page history of the Scottish Enlightenment and, honestly, I may as well just start it again now, because I cannot remember a single thing. I can barely remember where Scotland is.

I never went to drama school, I don't have any certificates saying: 'He's a qualified actor.' But I did think that 'House' was something I didn't have to apologise for. It was something I was really proud of and it was sort of... whether you liked it or not, it was undeniable.

I personally believe that the iPod is a frankly corrosive device because it encourages you to surround yourself with your favorites. The whole idea of a playlist is to surround yourself with your favorite things, and the interesting thing is that when you do that, they cease to be your favorites.

I really do believe the camera steals the soul. But that may be because I'm worried about my soul. I don't have much of a soul to begin with; I can't afford to lose much.

I think actors are attracted to the idea of other identities and concealing themselves behind some other identity.

I think good-looking people seldom make good television. And American television studios almost concede before they start: 'Well, it won't be good, but at least it'll be good-looking. We'll have nice-looking girls in tight shirts with F.B.I. badges and fit-looking guys with lots of hair gel vaulting over things.'

I think maybe even one of the reasons I became an actor was actually to hide. I mean, it sounds paradoxical because, of course, people are standing up in a public place and encouraging other people to look at them. So that's not the conventional definition of hiding.

I think my father gave me a great reverence for medical science. He was about as opposite to the personality of House as one could imagine. He was polite and easygoing, and would have gone to great lengths to make his patients feel attended to and heard and sympathized with.

I think of House as a deeply moral character, though some would no doubt argue with me. He does not judge. Beyond his normal tetchiness, there were no more than a half-dozen moments of actual condemnation from him. He understood lies and also why you lied, and there was an absolution there that is very, very appealing.

I think pain is a very - it's an extremely hard thing to empathize moment to moment. And you often don't remember your own pain, you know, that moment that you broke a limb or you burned yourself or, I think, this is a common thing that women talk about with childbirth, that the memory of the pain is hard to summon up and relive, thankfully.
