I work so hard to make that sure I'm successful. If you're positive and really excited and enthusiastic about what you're doing, it's going to happen, and it's going to happen big time.

It's extremely important just to keep things positive and happy as much as we can... I think it's important that singers, actors, or whatever use our voice to spread positive messages as much as we possibly can.

It was incredible being on tour with Taylor Swift: she was the epitome of a professional, and she works so hard. For someone as successful as her to work that hard every night - truly inspirational.

I'd be happy if anyone wore my fragrance. They don't have to be famous.

You just have to play it cool. You don't want everyone to know you're an amateur.

Being a sex symbol isn't cool unless you're in love with a girl, and she calls you a sex symbol.

At 13, I loved how so many of my peers sang and played acoustic guitar, so I started recording videos with covers of famous songs and posting them online.

I love Australia; it was a really, really nice experience for me. It's such a beautiful place. The people are beautiful - like, really beautiful - and they are beautiful in terms of their personalities. It's a great place to be. It's like you are in a little bit of a dream world.

I feel very comfortable with the U.K. tone and humour and laid-back attitude.

My mom says I'm not allowed to move out, but I'm allowed. I said I have to FaceTime her every night to make dinner with her because I won't be able to do it myself. So she said she'll accept it if I do that.

I'd say some of my earliest scent memories are from home - just things that were around my house, and my mom's cooking.

I feel like every time I write a song, it feels like the first time I wrote a song. It's just as hard; it doesn't get easier, but that's why I love it: because it's a challenge every time. I also feel like I'm learning new ways.

I'm very, very amateur, which is funny because I'm not in the amateur leagues.

Chance The Rapper is just unreal: he's changing rap and really creating this whole amazing new style.

I was one of those kids who was just always on the Internet, always on YouTube, so it was easy for me to do it. It's not work. It's just fun.

Growing up in a suburban home, the world seems so massive to you. It seems like cities are so big and so far away, and there's so much in them. So your imagination runs wild, instead of when you are born in the middle of Manhattan, you'd know, like, that this is the biggest city.

It's hard for me to just say, 'Wow, this is amazing - I'm famous. I'm living the dream.' I sit there and think, 'I'm scared - this can go away tomorrow.' My dad always says that I'm a tortured soul because I'm never pleased; I never feel like I deserve what I've achieved.
