You want to try and bring a character to life in an honest a way as you possibly can. It doesn't matter whether he's a doctor an actor a car salesman or a captain of a starship. If you can bring truth and honesty to that character then your audience will believe you.
I think basically becoming famous has taken the place of going to Heaven in modern society hasn't it? That's the place where your dreams will come true. It's an act of faith now they think that's going to sort things out.
