Self-defense is so important to know in today's society. It's not just that you might get mugged. It's more for confidence. It's the way you hold yourself when you walk into a room. Every step you take is more sure and you're much more aware of your surroundings. So, I think it's a really important thing - especially for women.

Music for me is something I prefer to keep away form the whole business part of my life. I feel like everything I do, in a way, has some sort of business around it. So with my music I can have my privacy. If people don't have to pay for it then I think they can be a little more open to new ideas.

I started super young, but when I think about myself at that age - what I thought I knew, and how priggish I was, how certain of things - now I realize that nothing is certain.

When I think about myself at 15, I can't relate to myself at all. I thought I knew everything.
