We've all heard the expression "fat and happy" -- it's hard to imagine someone described as "fat and happy" getting a lot of things done.
But what is that, what do people mean by the phrase? Certainly there's some portly jovial people who achieve things, no?
"Fat and happy" seems to relate to being satisfied more than anything else.
We all need a measure of satisfaction. When you can't get no satisfaction, you're driven to fix, change, improve things.
There is a a path of neutral equanimity, an egoless path which transcends the needs for self-gratification.
