Marcus Aurelius quote
Given the material we’re made of, what’s the sanest thing that we can do or say? Whatever it may be, you can do or say it. Don’t pretend that anything’s stopping you.
You’ll never stop complaining until you feel the same pleasure that the hedonist gets from self-indulgence—only from doing what’s proper to human beings as far as circumstances—inherent or fortuitous—allow. “Enjoyment” means doing as much of what your nature requires as you can. And you can do that anywhere.
