Bieber has been diligent in shedding his bad-boy persona, but says in retrospect, he doesn't have many regrets about that time in his life. "Everyone when they start growing up realizes, 'Man, I did some dumb sh** when I was younger,'" he says. "It's not just me. ...If I could go back I wouldn't really change much. I think it’s all my journey. That stuff made me who I am."
He also clarified that his hit single "Sorry" isn't a personal apology for his behavior in years past. "People ran with that -- that I was like, apologizing with that song and stuff," he explains. "It really had nothing to do with that. ...It was about a girl."
The release of Bieber's album, Purpose, marked something of a comeback for the singer after he had been plagued with heartbreak (Selena Gomez) and scandal. "I'm stubborn and I've always been really stubborn," he told ET prior to the album's release. "I think if I would have just known I could have been myself, but I don't think I knew my self-worth enough. I think that comes in time."
