How can a foreigner pursue their dreams in South Korea?

Recently, I saw a user asking about their dreams and then deleting their post. That user, like everyone else, deserves to pursue their dreams. If that dream positively impacts students and involves teaching English well, then definitely go for it. As a foreigner, realizing your dreams in Korea may not be easy. Especially in areas like Gangnam and Itaewon, there might be challenges in adapting as a foreigner. However, you hold value beyond just living without harassment. You should unleash your potential and chase your dreams. Is there anyone who can share advice or experiences on what a foreigner needs to pursue their dreams in Korea? I would particularly like to hear from those interested in education or other fields.
