what is contentment vs hapiness

Aristotle separates hedonia (pleasure, the feeling) from eudaimonia (flourishing, the condition). I keep collapsing them. I think I've been treating happiness as something that happens to you and contentment as the budget version. But Aristotle seems to suggest it's the opposite: eudaimonia is more stable precisely because it doesn't require a cause. You don't need good news to flourish. Maybe contentment is the ambitious one and I've been chasing the cheap version all along.
