At 35, I'm definitely starting to feel more like a grown-up than I ever have. There's nothing in my life that is childish or whimsical. Having fun is fantastic and I never want to lose a sense of that - and also, I think, you have to have that to put into your work or else it's going to feel stiff.
I never felt like I belonged in Minnesota when I was growing up there. That's why I was out the door as soon as I turned 18.
