The wise man is content with himself.
The wise man lacks nothing but needs much, whereas the fool needs nothing but lacks everything.
This isn’t as highfalutin as it sounds.
The fool needs nothing, because he doesn’t know how to use anything. And, being a fool and not knowing how to use anything, he lacks everything.
The wise man needs much: he needs his body, his mind, his tools, material to manipulate, etc. But he lacks nothing, because lacking something would imply that thing is a necessity, and nothing, to the wise man, is a necessity.
