A great, a good, and a right mind is a kind of divinity lodged in flesh, and may be the blessing of a slave as well as of a prince: it came from heaven, and to heaven it must return; and it is a kind of heavenly felicity, which a pure and virtuous mind enjoys, in some degree, even upon earth.
Seneca the YoungerThe condition of all who are preoccupied is wretched, but most wretched is the condition of those who labor at preoccupations that are not even their own, who regulate their sleep by that of another, their walk by the pace of another, who are under orders in case of the freest things in the world-loving and hating. If these wish to know how short their life is, let them reflect how small a part of it is their own.
Seneca the YoungerWhat difference does it make how much there is laid away in a man's safe or in his barns, how many head of stock he grazes or how much capital he puts out at interest, if he is always after what is another's and only counts what he has yet to get, never what he has already. You ask what is the proper limit to a person's wealth? First, having what is essential, and second, having what is enough.
