I'm just tired; I just want the world to be quiet for a bit.

My mind is a chest of drawers. When I wish to deal with a subject, I shut all the drawers but the one in which the subject is to be found. When I am wearied, I shut all the drawers and go to sleep.

Six hours sleep for a man, seven for a woman and eight for a fool.

Nature has not intended mankind to work from eight in the morning until midnight without that refreshment of blessed oblivion which, even if it only lasts twenty minutes, is sufficient to renew all the vital forces.

I try to not work too many Sundays. At least on Sunday nights, I try to chill out a little bit. I call it Sunday Funday.

You must sleep sometime between lunch and dinner, and no halfway measures. Take off your clothes and get into bed. That's what I always do.
