I can't sleep in the evenings. Most of the pictures people see of me are me going to work events: a Fendi dinner one night, a Prada dinner the next, and working all day.

I record all night and sleep all day.

I'd rather work all night and sleep all day... perhaps I was a mole in my last incarnation.

My father would often work all night and sleep during the day, so for us, dinner might be pancakes, and breakfast might be beef stroganoff.

I'm constantly feeding my metabolism. But at the same time if I want to go one night and have a nice dinner then I won't sweat it the next day.

I played a lot of night matches, ... People have finished a long hard day of work and they try to loosen up a bit. The players have more time to get worked up and get themselves psyched up. There's just an energy there that lends itself to more unpredictability but also, in a lot of cases, some greater tennis.
