Meditações - This household has no clocks. Nor calendars

„Dr. Russell, I concede that Washington has an atrocious climate. But you will have air-conditioned offices.” 

“With clocks, no doubt. And secretaries. And soundproofing.” 

“Anything you want, doctor.” 

“The point is, Mr. Secretary, I don’t want them. This household has no clocks. Nor calendars. Once I had a large income and a larger ulcer; I now have a small income and no ulcer. I stay here.“ 

Robert A. Heinlein, in Have Space Suit—Will Travel (1958)
