Cameron Russel gives a TED talk about being a model. 

“I am insecure. Because I have to think about what I look like every day. If you ever are wondering, ‘If I have thinner thighs and shinier hair will I be happier?’ you just need to meet a group of models because they have the thinnest thighs and the shiniest hair and the coolest clothes and they’re the most physically insecure women on the planet.”
