Even though I need only two or three hours' sleep a night, there are never enough hours in the day.

I work 18 to 20 hours a day, seven days a week, so I don't have time for a social life. Or any life outside work.

You only get one life. You have to do what you feel is right with it.

I usually sleep just a few hours a night.

When vultures sleep at night, they drop their body temperature. During the day they spread their wings to raise their body temperature.

I record all night and sleep all day.
