As a person born in North Carolina and raised in an Eastern Asian country until the age of seven, I sort of HAD to adapt to both cultures at the same time. It had been difficult to adjust to a completely different language, but I had the chance to grow up around many different cultures and ethnicity. Technically, I didn't have much trouble on picking which culture to go along with, no society is as traditional as it had been just a few years back, the world is actually rapidly merging together.

Like any stereotypical Asian family is perceived, my parents and relatives all have high expectations in education, but I get to have much more free time than my cousins in Taiwan. My parents' strictness really wore off after living in the United States for so long, the expectations of certain societies can greatly affect one's perspective. I try live up to my parents' expectations by turning in school work on time, but really don't study as much as before anymore.
I typically follow the "mainstream" events from both cultures and am willing to accept more, but I am still able to tell the difference between what right or wrong to go along with. By being not as traditional as people my counterparts of the same ethnicity and being more open in accepting the unknown, I think this is the right way to retain and learn cultures.
