It sounds like a cliche but I also learnt that you're not going to fall for the right person until you really love yourself and feel good about how you are.

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.

Who here actually thinks I would do 50 Shades of Grey as a movie? Like really. For real. In real life.

Even worse than seeing women's privacy violated on social media is reading the accompanying comments that show such a lack of empathy.

I didnt know there were so many ways you could walk down stairs until the day we filmed Hermiones entrance into the Yule Ball Hall.

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

You might be thinking who is this Harry Potter girl? And what is she doing up on stage at the UN. It's a good question and trust me I have been asking myself the same thing. I don't know if I am qualified to be here. All I know is that I care about this problem. And I want to make it better.
