I don't take pictures when I'm with my kids, for the sake of my kids. It's important when you're as busy as I am that you give your kids your time when you're with them, and nothing compromises that. I've been lucky enough to have fans that understand that.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.

It's fun and super exciting to see how other people work, how other people write music, and how other people put things together. To me, it's an endless learning process, and I love doing it because everybody works so completely differently.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
