Leisure Time

This is very important -- to take leisure time. Pace is the essence. Without stopping entirely and doing nothing at all for great periods, you're gonna lose everything...just to do nothing at all, very, very important. And how many people do this in modern society? Very few. That's why they're all totally mad, frustrated, angry and hateful. -- Charles Bukowski

Here's another one I like:

Some lose all mind and become soul,insane.
some lose all soul and become mind, intellectual.
some lose both and become accepted
-- Charles Bukowski

Presumably there is a 4th type that manages to keep both mind and soul...
