My best friend Madison keeps a list on her phone of all of the different English slang that I say, so she has kind of like a translator so she can understand without having to ask me, "What on Earth are you talking about when you say 'nackered'?"

But sometimes I've felt a little constrained by that idea of who I'm meant to be.

Concentrate on comfort - even if that means wearing the same thing over and over, because when I feel comfortable, I feel so much more relaxed and have a much better time.

As a younger woman, that pressure got me down, but I've made my peace with it. With airbrushing and digital manipulation, fashion can project an unobtainable image that's dangerously unhealthy. I'm excited about the ageing process. I'm more interested in women who aren't perfect. They're more compelling.

I really want to write a novel. I also want to learn to play the mandolin.

I threw my 20th birthday party at Brown, and I didn't even have to say to anyone not to put pictures on Facebook. Not a single picture went up. That was when I knew I'd found a solid group of friends, and I felt like I belonged.

I went from being totally unknown and never acting professionally to being in a major movie and being very famous. It all happened so quickly, I didn't have any time to work things out. It's been pretty scary at times.
