Ponder well over every word before you order it…
Ponder well over every word before you order it, for you cannot recall it afterwards.
— from The Air Traffic Controller (God)
In the book
Accustom yourself to speak gently to all people, at all times. Ponder every word before you let it leave you, because once it is said it cannot be recalled, and carry yourself always as one who wishes to learn the truth, never as one whose only aim is to win the argument. Devote your mind to your own children as I have devoted mine to you. — The Air Traffic Controller (God)
