Happiness according to Aristotle

Happines, he maintained, is made up of three sorts of goods: goods of the soul, which he indeed calls the foremost in importance; socondly, goods of the body: health, strenght, beauty, and the like; and thirdly, external goods: wealth, noble birth, reputation, and the like.
He held that virtue, by itself, is not sufficient to ensure happiness; bodily and external goods are also necessary, since the wise man will be wretched if he lives in pain, poverty, and the like.
Yet vice, by itself, is sufficient to ensure unhappiness, even if abundant bodily and external goods accompany it.

Aristotle on moderation

Mankind, he used to say, was divided into those who were as thrifty as if they were going to live forever, and those who were as extravagant as if they were were going to die any moment.
