A quote
We hold nothing dearer than a benefit, so long as we are seeking one; we hold nothing cheaper after we have received it. Do you ask what it is that makes us forget benefits received? It is our extreme greed for receiving others. We consider not what we have obtained, but what we are to seek. We are deflected from the right course by riches, titles, power, and everything which is valuable in our opinion but worthless when rated at its real value.
Seneca·Letter 81 (§28)·trans. Gummere
