Remember that you ought to behave in life as you would at a banquet. As something is being passed around, it comes to you; stretch out your hand, take a portion of it politely. It passes on; do not detain it. Or it has not come to you yet; do not project your desire to meet it, but wait until it comes in front of you.–Epictetus, c. 135
Epictetus was a Greek sage and Stoic philosopher. The major compilation of Epictetus’ teachings are the four-volume work standardly referred to in English as the Discourses.
