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.

When you look at Steven Meisel's pictures and you see girls rolling around in mud or cars are blowing up? It takes a tremendous amount of courage to be able to do that. I think you have to be malleable, and that's what makes a truly great model. It's not the perfect lip or the perfect face, it's your own ability to take on a character and that's, I think, something there's a misconception about.

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.

Natural talent means to have the ability to transform, to evolve, to play and role-play with the photographer and the stylist. And really be an actress rather than just a mannequin. So that involves a tremendous amount of confidence and your ability to expose yourself to anything that will make a better photograph.

America has always been the most fertile ground for models - and they were always exported to other countries. When Eastern Europe opened up its doors to the rest of the world, a lot of the girls that were basically working there for $1 a month realized that if they were beautiful and that they could go to Paris and work for $1,000 a day versus the $10,000 that the other girls were demanding. So it created a huge imbalance in the financial structure of how clients could budget out campaigns. The market became flooded.

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.
