Scholars and researchers have tried to discover what personality characteristics go along with success in different cultural experiences. Their findings have often been unclear or incomplete. But three typical characteristics stand out in their reports: patience, a sense of humor, and the awareness of being unclear.

    Patience, of course, is the ability to keep calm when things do not go as one wants them to, or as one hopes they would, or even as one was sure they would. Impatience sometimes brings improvements in relations with other people, but usually it does not.

    A person with a sense of humor is less likely to take things too seriously and more ready to see the humor in his own reaction than a humorless person. The value of a sense of humor really needs to be paid more attention to.

    “The awareness of being unclear” is a more difficult concept to understand than patience and a sense of humor. Foreigners often find themselves in situations that are unclear as they are newcomers. That is, they do not know what is happening in a certain situation. Perhaps they do not understand the local language well enough, or they do not know how some system or organization works, or they can’t be sure of different people’s roles in what is going on. “It’s like that I just got here from the moon,” a Chinese graduate student who newly arrived in the United States said. “Things are just so different here.”
