The 22-year-old actress feels like she lives two separate lives because she gets to go to glamorous events as a celebrity but also do normal things that youngsters do.
She explained: "I find myself living in two worlds sometimes--being this person who can walk a red carpet in a huge, fancy-ass ball gown, high heels and mountains of makeup, but also being the girl at a hippie festival in the middle of the forest with war paint on my face, dancing around with hairy armpits. I exist so well in both, and I used to feel like I had to choose one or the other.
"I struggled with that up until doing 'The Fault in Our Stars' . I have one life to live, and it could end any minute, so I'm going to appreciate every single moment. I'm going to own my day before my day owns me."
The brunette beauty believes she's remained level-headed because she's ignored negative comments and focused on her blossoming career.
She explained in the May/June issue of Natural Health magazine: "Someone once told me that it's none of my business what anyone else thinks of me. That was an epiphany. The thing about this industry that ungrounds people so often is fear. It's the fear of not being accepted, not being enough, being compared, not being this or that...It's just clutter! It just doesn't need to be there."
