Someone once said, "You go to New York to become someone, you go to L.A. when you are someone, and you go to Miami when you want to be someone else."
We like to think we're somebody, but it would totally make sense if we found out we had been someone else our whole life. It takes a certain kind of special to make Miami work. You can't have too many hangups. You've got to be OK with tacky and classy being approximately the same thing. You've got to be chill and kind of a bitch all the time. It takes practice.
Some people will just never get it right, and that's fine. For them, there's New York or L.A. or whatever.
