Stoicism in a Nutshell

"So now the threads of the sections can be tied
together. Someone who judges truly will never be unhappy,
will in fact experience continual uninterrupted appropriate
positive feelings, and will always act virtuously. Anyone
would agree that someone who led a life like that was
happy. Judgment is in our control. Hence, not only is
prefect continual happiness possible, it is actually in our
control--we can actually guarantee it by simply judging
correctly, and acting on those judgments."
