Joe did cocaine and alcohol for about three years while working in Hollywood. He managed to quit his addiction on his own without going to a rehabiliation center.
As a reminder of the brutally hard times during Joe's slow and painful climb to stardom he keeps a photo of himself, when he was 19 years old, on the dining room wall.
Joe: (on being popular) When you're popular, you're always on the go. When you have spare time you want to use that spare time to continue on with your career. You tend to think that I am my job, I have become my job.
Joe: (on work substituding for a wife and kids I don't know if that's a healthy thing. A lot of people think I'm not a friendly guy. I'm pretty quiet, not an extrovert. I don't think about how great I am and all that...I like to go places by myself. I don't go out with an entourage. And I get so tired of me. This is a pretty self centred job. They're making you up. The executives are talking about you. The writers are writing for you. I get so tired of talking about me. I like to unplug the phones and 'zone out'.
