Wealth consists not in having great possessions, but in having few wants.

following Epicurus- Greek philosopher (341-270 BC), following a longer passage in his “Letters to Menoikeus” (130, 5-8), Quotations book 2007

The Original says:

Καὶ τὴν αὐτάρκειαν δὲ ἀγαθὸν μέγα νομίζομεν, οὐχ ἵνα πάντως τοῖς ὀλίγοις χρώμεθα, ἀλλ’ ὅπως, ἐὰν μὴ ἔχωμεν τὰ πολλά, τοῖς ὀλίγοις ἀρκώμεθα, πεπεισμένοι γνησίως ὅτι ἥδιστα πολυτελείας ἀπολαύουσιν οἱ ἥκιστα ταύτης δεόμενοι.

We hold that self-reliance is a great good — not so that we will always have only a few things but so that if we do not have much we will rejoice in the few things we have, firmly persuaded that those who need luxury the least enjoy it the most.
