Tamara Rojo was principal ballerina for Royal Ballet. I really identified with what she said in an interview with The Guardian this week.

She says she still loves performing, “but really truly good performances are few and far between – I can maybe count 10 in my whole career.”
She usually comes out disappointed with herself. “It’s an alchemy, something beyond your control. It’s almost like you come out of yourself, you become something bigger than yourself – something else did take over.”

In that constant pursuit of that one magical night, perhaps only the 11th time in a career spanning more than 20 years “you keep working. That’s the hook.”
