I'm staring down the end of a huge TV camera lens, waiting for my interview with CNN to begin. It's a nerve-wracking situation. I have no idea what questions the news anchor will ask or how friendly she will be. I'm nervous, but what kind of nervous am I feeling? Just knowing I'm nervous isn't helpful enough to know how to make myself feel less nervous. My ability to stay calm and focused in that moment—my ability to succeed—depends heavily on my ability to know the answer to that one question.
