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.

There's something I call telegenekicity, and it's not about just models. Of course, I can reference Iman, Tatiana Patitz, Kelly Emberg, Bonnie Berman - I go all the way back - but I think that you develop an eye to register iconic images - like Greta Garbo and Elizabeth Taylor.

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.

A lot of people don't make the correlation between acting and modeling, they think of them as two separate things. But I really believe that a model is an actress.

When you see someone, you automatically start putting those people together - the eyes and the lips. And what that does is that it creates an identity with that person, so when they actually start working, the audience sees exactly what you're seeing, and they become recognizable. So instant recognition is when certain women and men have features that look like other people. So baby Gisele is, like, Linda V - that's what she was called for a long time.

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.
