David Carr interviewing Mike Tyson at Sundance about the new documentary, Tyson:

Tyson: I'm getting over all this, all these cameras. That's a straight ticket back to picking up cocaine. All of this is very frightening and intimidating.
Carr: Will you tell me more about how that becomes a trigger. I just walked down the street with you, and I couldn't stand being that closely observed, I couldn't stand people swarming around me. How does that impact how you see yourself?
Tyson: You being a former addict yourself, I don't know how it works in your particular situation. But I never get high because I'm depressed or sad. I always get high because everything is going great.
Carr: Right. Everything's going your way.
Tyson: Do you understand that?
Carr: Oh, absolutely.
