"You must sleep sometime between lunch and dinner, and no half-way measures.
Take off your clothes and get into bed. That's what I always do.
Don't think you will be doing less work because you sleep during the day.
That's a foolish notion held by people who have no imagination.
You will be able to accomplish more.
You get two days in one-well, at least one
and a half, I'm sure. When the war started, I had to sleep during the day because that was the only way I could cope with my responsibilities."
-Sir Winston Churchill
