Lack of discipline. First of all, I think some of them fail because they just don't have natural talent, and they shouldn't even be in the business to begin with.

A girl's career today doesn't have the same kind of life span, whereas it used to be a collaboration and a partnership and it continued. Peter Lindbergh still uses girls - like, look at Amber Valetta - so there are some photographers that have relationships long-term with models. I also think that the industry can't support the amount of models that exist right now and therefore the relationships between photographers and models and even the clients is short lived.

I think as a scout you have to pick. It is harder. You have to talk and explain that this is not just about standing one-dimensionally in front of a camera.

Today they have to be three-dimensional. Technology's changed, the communication, the marketing and advertising community supports beautiful girls that can be articulate and smart. And also Anna Wintour doesn't want to sit next to some girl who can't say two words.

You have to look for a unique quality in that person and it's not just always physical. I don't think models are great models because of their face or their body. Obviously, I think their physical characteristics are important, but I think it's very much about your personality and inner beauty and really understanding how to be a great model instinctively. And that's where it all comes from.

Now people are much more receptive because they can just go online and just Google your name and make sure you're not, you know, psycho. But, before, I think lot of opportunities were missed by a lot of girls. Also parents! The girls would go home and would say, "Oh, you know, I was just scouted." And the parents were, like, "You're not going to be a prostitute."

If you look at the greatest models, it was because they were muses to photographers. They collaborated with the artist and they created the kind of images that become iconic.
