I worry that if I enjoy something - like the songs on 'Some Nights' are about wondering about who you are. I'm never quite sure and I'd hate to feel sort of content and get a good sense of who I am because if I know one thing, that's not me. I don't mind not necessarily being happy about it. And that's fine.

My girlfriend is a fashion designer. She has her own company called Rachel Antonoff. She is doing a collaboration with Urban Outfitters right now, a shoe collaboration with Bass. She sells to Barneys, stuff like that.

I try and get about eight hours of sleep every single night. And I like to think that I drink more water than anyone, ever.

I never wanted to get a job of musician. That was kind of my thing. I came from somewhat of a musical family. I had an uncle on Broadway. My dad kind of knows how to play instruments. Although, I always find it annoying when he does play an instrument.

In a city like New York, any night can be completely different, even in a subtle way.

I don't play an instrument - I just write in my head, and I usually hear fully formed songs. 'We Are Young' turned out so much like it was in my head. But it also exceeded all my expectations.

But as long as you're creating the art you want to create, if people start liking you, you shouldn't have to apologize. You want your stuff to be heard by as many people as possible.
