Together with a culture of work, there must be a culture of leisure as gratification. To put it another way: people who work must take the time to relax, to be with their families, to enjoy themselves, read, listen to music, play a sport.

Every now and then go away, have a little relaxation, for when you come back to your work your judgment will be surer. Go some distance away because then the work appears smaller and more of it can be taken in at a glance and a lack of harmony and proportion is more readily seen.

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.

Sleeping is no mean art: for its sake one must stay awake all day.

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

The natural thing to do is to work-to recognize that prosperity and happiness can be obtained only through honest effort. Human ills flow largely from attempting to escape from this natural course. I have no suggestion which goes beyond accepting in its fullest this principle of nature.
