It makes me sad to hear girls constantly putting themselves down. We have these unbelievably high expectations of ourselves, when actually we're human beings and our bodies have a function.

What I find difficult about photo shoots is the line between playing a character - you're being asked by the photographer to take on a role like you would in a movie - and being a fancier version of yourself. It's about finding that line between being spontaneous and open to direction, but also trying to explain to photographers that the "me" is often taken out of context because it has all of this other stuff attached to it.

I find it easier to cry than I do to laugh convincingly. It's incredibly hard to pull off a laugh that feels natural take after take after take, that feels real. You can tell a fake laugh the minute you hear it, and that's something I really struggle with more than producing tears.

Most people are really nice but some stare, like you're some kind of zoo exhibit and not a real person with real feelings.

Young girls are told you have to be the delicate princess. Hermione taught them that you can be the warrior.

Becoming yourself is really hard and confusing, and it's a process. It's often not cool to be the person who puts themselves out there.

Being asked to serve as UN Women’s Goodwill Ambassador is truly humbling. The chance to make a real difference is not an opportunity that everyone is given and is one I have no intention of taking lightly. Women’s rights are something so inextricably linked with who I am, so deeply personal and rooted in my life that I can’t imagine an opportunity more exciting. I still have so much to learn, but as I progress I hope to bring more of my individual knowledge, experience and awareness to this role.
