I was really scared that other girls hated me, that I wasn't pretty enough or cool enough or I didn't have enough Instagram followers or whatever. Finding female friendship was such a monumental point in my life. And I never want somebody to feel like they have to re-evaluate themselves to join my friends or to join any friend-group.

I understand Twitter much more than I understand Tumblr.

The friendship that you create between you and a mom - or you and an older woman figure - is so important and so influential. I think that my relationship with my sister, my relationship with my best friends - when I'm feeling really terrible about myself, they're always there to let me know that I am being dramatic about something, or I'm being stupid about something - it's good to have those kinds of people to drag you back down and protect you.

I genuinely love to be by myself, but at the same time, it's such a relief to know that I have another person's head who I can go into and whose life I can live. It's kind of an escape route, almost like therapy. It's refreshing to know that I can go back to a place where I don't have to be myself.

I think something that I've learned from other actresses is to really take the time to get to know yourself, especially because I think that your sense of self is easy to lose when you're playing other people.

Teenagers have a legitimate voice. We deserve to have a seat at the table and a place in the conversation. We're not exempt from politics and social movements; we're affected by them.

The Catcher in the Rye had such a deep impact on me, because it felt like it was just Holden and me. I didn't feel like any other person had read that book. It felt like my secret. Writing that I identify with feels like it's just me and the writer. So I hope that whoever is reading what I do feels like that.
