By self-analysis you can not change your character, but you may change your mentality.
My way in for photographing people is really their work. I'm always interested in what people make, and then I photograph the person. Sometimes the person is a disappointment. But that's the risk. It informs me a lot about the character of a person if I know their work first.
Like stories, people have individual lives, and are all caught up in this murky thing. All of them have the best intentions. In that sense, you could just as easily tell the same story from another character's perspective. Maybe that's a good idea for a TV series.
