The trick to being successful as an ABC in Taiwan is to stop competing as a foreigner, because Taiwanese people will never fully accept you as a foreigner and will just see you as a fake. Instead, market yourself as a Taiwanese person with Western abilities just as good as a foreigner's. That's how you become the "best of both worlds".
I'm not saying I agree with this; I'm just explaining how it is.
It has been 3 years since I've moved back to Taiwan. I've always had a hard time with the people, culture, and the working environment. Upon reading your post, I have had one of those "AHA!" moments. I guess I finally get it. Thanks Amasashi.
