I've studied a technique called the Sanford Miesner technique that teaches you how to focus. It's mainly about daydreaming. And the technique's really about imaginary circumstances. Using your imagination to sort of daydream about stuff. It makes you emotional in a scene.
I have a huge breakfast every morning because I never know if I'll have time for lunch especially during Fashion Week. It keeps my mood positive all day. And my parents taught me to have tons of fruit and vegetables which I think helps my skin.
