Leven: I think it's important for all teens to understand they can be active in their communities and make a big difference with the proper outlets and help.
Leven: (on Ashton Kutcher's prank show "Pop Fiction") I love it, I love it! I really want to do that. I'd have to think of something really creative and mind-fucking. Maybe if I adopted a child, like a foreign child, and carried it around and took it to work and took it to a Teen Vogue party. That'd be pretty funny.
Leven: (on hosting a number of Cure Autism Now campaigns) I'm glad that I can put a face to a cause, because it's a really interesting topic. If I can draw more attention to it, I think that's really the best thing that I can do for it. I hope to be more alluring to whoever wants to cure autism.
