Stoics say that being happy is the goal for the sake of which everything else is done, for the sake of nothing else; and this consists in living according to virtue, in living in agreement, and (which is the same thing) in living according to nature.

A Reaction
The best summary I have found of the main stoic goal. Stoics are eudaimonists. The full stoic story must explain how virtue, agreement and nature fit together into a coherent whole.
