Turn your back on no one. Be as happy as you can. Be culturally sensitive, but also culturally wary. Have a good attitude. These may sound like common sense.
Life everywhere is better with a dose of common sense.
Don t overanalyse your life in South Korea, it will only get you down. Turn your back on no one. There are two parts to this rule. The first is simply to pay attention to other people. In other words, be social.
