Seneca,
Moral letters to Lucilius — Letter 119…
“ That is deceit – showing me poverty after promising me riches." But, friend, do you regard a man as poor to whom nothing is wanting? "It is, however," you reply, "thanks to himself and his endurance, and not thanks to his fortune." Do you, then, hold that such a man is not rich, just because his wealth can never fail? 6. Would you rather have much, or enough? He who has much desires more – a proof that he has not yet acquired enough; but he who has enough has attained that which never fell to the rich man's lot – a stopping-point. ”
