Harapan adalah jalan menuju kebahagiaan. Jika kamu ingin bahagia, kamu harus memiliki harapan. - Epictetus

First learn the meaning of what you say, and then speak.

Consider when, on a voyage, your ship is anchored; if you go on shore to get water you may along the way amuse yourself with picking up a shellfish, or an onion. However, your thoughts and continual attention ought to be bent towards the ship, waiting for the captain to call on board; you must then immediately leave all these things, otherwise you will be thrown into the ship, bound neck and feet like a sheep. So it is with life. If, instead of an onion or a shellfish, you are given a wife or child, that is fine.

If a person gave your body to any stranger he met on his way, you would certainly be angry. And do you feel no shame in handing over your own mind to be confused and mystified by anyone who happens to verbally attack you? (28) [tr. Elizabeth Carter]
