I play drums and guitar. My best instrument is definitely drums, so I'm featured a lot on the album drumming. It's pretty futuristic as well.

I think love is like a learning process throughout your life. You learn how to be better at it and you learn more about it.

The Beliebers have done some pretty crazy stuff. Last week, the night before I was due to do a show in Germany, four girls went into a dumpster so they could sneak into the building. They climbed in and hid. When the guys working on the truck started getting the garbage they found them straight away. It was crazy.

People write to me and say, 'I'm giving up, you're not talking to me.' I just write them a simple message like, 'Never give up,' you know? And it changes their life.

Never stop dreaming, because dreams DO come true.

Not everyone's going to like my music. People might not like my music, because I'm just not their style of music that they like to listen to.

I've got such great people around me. They don't really care if they make me angry. A lot of teams, they're afraid to make the artist angry, because they don't want to get fired and all that stuff. My team's pretty good about letting me know when to get in line.
