Thou shalt not expect to find things as thou has at home, for thou has left home to find things different

Thou shalt not worry, for he that worries hath no pleasure and few things are that fatal

Thou shalt know at all times where thy passport is, for a person without a passport is a person without a country

Thou shalt not let other travelers get on they nerves, for thou has paid good money to enjoy thyself. 

When in Rome be prepared to do somewhat as the Romans do

Thou shalt not take anything too seriously for a carefree mind is the start of a good holiday

Remember thou art a guest in other lands and he that treats his host with respect shall be honored

Thou shalt not judge the people of the country by the person who hath given the trouble

Thou shalt pack light …REALLY light.
