My power of speech, unimpeachable. Only 19 but my mind is older.

I think you balance the things you've been dying to do all your life. And the opportunities that come along, that you didn't maybe think of, that are so amazing, that you'd kick yourself if you didn't try to be a part of them.

I'm not going to hang out with celebrities, I'm not going to parties. I have two songs due for Moana next week, and I'm going to go and spend some time with Maui and Moana in the ocean, in my mind.

I think, there are a couple of songs. I'm really proud of How far I'll Go. I literally locked myself up in my childhood bedroom at my parents' house to write those lyrics. I wanted to get to my angstiest possible place. So I went method on that.

I still look at that water, and I look at Moana's hair, and I'm just like, "How is this even happening?" It's such an incredible mix of technical mastery and wizardry. It's really incredible. It's layers and layers and layers. It's not unlike building a musical. It's really pretty cool.

I felt so nourished by the process of making [Moana], of you're always engaged with other artists from different disciplines, and it's about bringing your art form to the table. It's so many art forms mashed together.

I got to holler just to be heard.
