Whether you're on TV or on the stage, you have to work hard to stay fresh, real, and full of energy. You can't settle back. You always have to stay on your toes.
Most achievers I know are people who have made a strong and deep dedication to pursuing a particular goal. That dedication took a tremendous amount of effort.
As far as pacing the shoot is concerned, I know when I've got it. I don't think there's any reason to take ten takes unless you need them.
