People used to always talk down to me, like, "Oh, you're so young," but now I recognize that my age is an advantage; there's a lot more I can do.

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.

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.

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.

That the things that have impacted me most are not news articles written by older people that I would have no relation to; the things that impact me most are things written by people closer to my age. And I wanted to write things in a way where somebody my age could read it and feel like they are holding somebody's hand and be with somebody.

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.

I have so many different role models who have taught me so many different things at so many different points in my life, it doesn't feel like I have one person that I have to live up to.
