I'm in the entertainment business, where you're only as good as your last show.

I think there's a kind of elegance to it, to work within that framework where what you don't see is often more enticing.

The weirdest thing with friends, the way you measure it is if you go without communicating for months at a time, you can sit down and within five seconds be right where you were. I know it's a cliché, but quality not quantity, and that bond will not disintegrate. It does need to be tended to but it won't go away. It's amazing, though - I'm here in New York where my best friend from college lives, and we see each other twice a year and we're right where we were and a lot of it's unspoken.

It took seven years from the time I wrote Mad Men until it finally got on the screen. I lived every day with that script as if it were going to happen tomorrow. That’s the faith you have to have.

TV writing is for people who hate being alone more than they hate writing.

I do find it sometimes that people project their own feelings on to the characters and I think that there is a certain amount of sexism - I mean the proprietary nature, for men and women.

But you know what, honestly? I'm not that interested in advertising. I think it's a great way... It's such a huge part of our culture. It's like saying, "Are you interested in hair?" It's such a part of our life, and it's such a reflection of how we feel about ourselves, and what we're interested in, and what we want to be.
