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

How well you treat the wicked people, they don't give up their wickedness. They derive pleasure in hurting others. A serpent made to drink milk, it ejects poison only.

Religion is preserved by wealth; knowledge by diligent practice; a king by conciliatory words; and a home by a dutiful housewife.

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.

Sleep is the best meditation.

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.
