South Koreans aspire to be the best. ‘Challenge’ and ‘fighting’ are imperative verbs plastered across billboards. From English-learning to b-boying, society is suffused with the message that if you practice for hours daily, for years at a time, you can succeed. For example, consider ballerina Kang Sue-jin, a master of her field. She is a principal dancer at Stuttgart Ballet and is widely admired for her strength, agility and beauty.
