What if democracy does not serve liberty? This question is seldom asked in the West, where democracy is often seen as synonymous with liberalism.

I used to refer to myself as a 'theoretical anorexic,' just as crazy when it came to body image, but saved by a lack of self-discipline. My daughters do everything better than I do - they're smarter, more beautiful, happier. What if they end up better at anorexia, too?

If I lose forcing the pace all the way, well, at least I can live with myself. But if it's a slow pace, and I get beaten by a kicker who leaches off the front, then I'll always wonder, 'What if...?'

I was honoured when they asked me to appear at the president's birthday rally in Madison Square Garden. There was like a hush over the whole place when I came on to sing 'Happy Birthday,' like if I had been wearing a slip, I would have thought it was showing or something. I thought, 'Oh, my gosh, what if no sound comes out!'

What if others suffer shipwreck, yet none that sail with Jesus have ever been stranded yet.

What if everything is an illusion and nothing exists? In that case, I definitely overpaid for my carpet.

You have to come to your closed doors before you get to your open doors... What if you knew you had to go through 32 closed doors before you got to your open door? Well, then you'd come to closed door number eight and you'd think, 'Great, I got another one out of the way'... Keep moving forward.

What if every relationship you've ever been in, is someone slowly figuring out they didn't like you as much as they hoped they would?

I think time travel is really tricky. But if there's a logic and a complete and well-thought-through paradigm for it, I think it can be really interesting. Some of my favorite time-travel movies just make me think and, you know, the 'what if' question becomes a big one.

Do it no matter what. If you believe in it, it is something very honorable. If somebody around you or your family does not understand it, then that's their problem. But if you do have a passion, an honest passion, just do it.

It's very dangerous to wave to people you don't know because what if they don't have hands? They'll think you're cocky.

People always tell me I'm going to regret not having kids. But what if I have one and then I regret having it? Has anyone thought of that option?

The Jetsons had them in the 1960s. They were the defining element of 'Knight Rider' in the 1980s: cars that drive themselves. Self-driving cars appear in countless science fiction movies. By Hollywood standards, they are so normal we don't even notice them. But in real life, they still don't exist. What if you could buy one today?

We have all loved a guy we know has issues. Despite popular opinions, until we give it a final try, the relationship will always be in the 'what if' stage.

We live in such a service-based, globalised economy where very few people actually make anything and the people who do make stuff... it's all part of a massive global supply chain. So what if all those chains were suddenly cut, how would you make something? How would you keep people alive? And that was something I wanted to explore.

I remember having a conversation with my sister, saying, 'What if I don't make it? What if I'm still waiting tables when I'm 35?' I was just at the end of my rope. But I've been at the end of that rope several times.

Couples in their 30s are having trouble having kids. And you just kind of extrapolate that and say, 'What if it happened to everybody? What kind of society would it be like if all of a sudden we knew that this was the end of the line - we couldn't have kids?'

What, if as said, man is a bubble.

I wish the media and people that work in media would realize sometimes - and I know it doesn't pay your bills - but sometimes just sit back and think, like, 'Man, what if this was my child? And somebody was doing this to them? And they had to go through it? If somebody bashed them like this?'

Instead of picking your career and backfilling your life behind that, what if you pick your life and backfill your career with whatever is left over?
