Leave All Behind

"On a voyage, when the ship is anchored, if you go on shore to get water, you may gather a small shellfish or cuttlefish along the way as a side issue for yourself, but your thoughts must be directed at the ship and you must be constantly watchful if not the captain calls. And if he calls, leave all of it behind, so you won’t be thrown into the ship bound like cattle. It is the same in life: if instead of a small shellfish and cuttlefish, you are given a wife and child, there is nothing against that. But if the captain calls, rush towards the ship and leave all behind without looking back. And if you are old, don’t even go far from the ship, so you won’t default when you are called."  (Epictetus)
