Korean Language Learning Retry: Inquiry About Effective Methods

Hello, I'm Ozzie from the United States. I paused my Korean language learning since last summer, but now I'm ready to take on the challenge again. I'm trying to reduce my use of Romanization and practice pronouncing each character directly while learning Korean. So, it's still not easy for me to form words quickly. If you have any effective methods or tips for learning Korean, could you share them? In particular, if there are any Korean study groups in areas like Gangnam, Hongdae, or Itaewon that foreigners can join, I would appreciate your recommendations. I want to improve my Korean skills while experiencing various cultures. I look forward to your advice!
