"I'm crazy, I'm nuts. Just the way my brain works," Justin Bieber told Vanity Fair for its current cover story. "I think differently -- my mind is always racing. I'm just...nuts. But I think the best [musicians] probably are."
Asked who he considers to be the best in music, he mentioned the Beatles, Michael Jackson and Tupac. And he said: "I'm definitely influenced by Michael Jackson and Boyz II Men and people who were black artists -- that's what I like."
Bieber also predicted that over time he will expand his fan base beyond its core females. "For younger guys, it's like they're not cool if they come to my concert," he told Vanity Fair. "That'll [change], I think; it'll happen, maybe when I'm 18."
The young music star also acknowledged that the stress of superstardom is a challenge for him at times. "It's hard to really balance myself," he said. "A regular kid, if he catches the flu, he just gets to go home. But I can't do that...Everything is important."
But he also vowed not to make bad life-changing decisions. "I've seen it happen too many times," Bieber told Vanity Fair. "I could be my own worst enemy, but I don't want to mess this up."
Discussing his insomnia, Bieber told the magazine: "I just turn over all night and think. My mind races. I think about all the things I didn't have time to think about during the day - like family and God and things that should be more important."
