Mark: I'm a big optimist. Negative thinking is such a waste of time. I have a friend who's a real pessimist. I said to him once, 'You know what your problem is? Your glass is always half empty.' And he said, 'No it's not. It's just not big enough.' My God, that is the ultimate pessimist. Some people feel the need to worry. I don't. Maybe I'm irresponsible, but I just refuse to deal with things like that. Why worry?

Mark: I've based my whole career on not giving a crap what people think. I have enough confidence in myself that it's like ... 'why would I care?'
