I have no idea where this originated, but it’s a gem my mother found tucked inside a book some 40-odd years ago and passed onto me while growing up. Substitute the words “expats” for “travellers”, “life” for “holiday” and your nationality for “English” and I think it’s not a bad “life manual” for those of us living abroad:

The Ten Commandments for Travellers

1. Thou shalt not expect to find things as thou hast them at home… for thou hast left thy home to find things different.
2. Thou shalt not take anything too seriously,,, for a carefree mind is the beginning of a fine holiday.
3. Thou shalt not let the other tourists get on thy nerves… for thou art paying out good money to enjoy thyself.
4. Remember to take only half the clothes you think you need… and twice the amount of money.
5. Remember thy passport so thou knowest where it is at all times… for a man without a passport is a man without a country.
6. Remember if we are expected to stay in one place we would have been created with roots.
7. Thou shalt not worry. He that worrieth hath no pleasure… few things are ever fatal.
8. Thou shalt not make thyself too obviously English… when in Rome, do somewhat as the Romans do!
9. Thou shalt not judge the people of a country by the one person with whom thou hast had trouble.
10. Remember thou art a guest in every land… and he that treateth his host with respect is treated as an honoured guest.
