Korean Language Learning: The Path from Beginner to Advanced Content

Hello, I am a foreigner learning Korean. I first visited Korea in 2011 and 2015 when I operated an English camp at a friend's uncle's church. I only learned Korean alphabet and basic grammar and lost interest. However, after marrying a Korean in 2019, I started learning Korean again to communicate with my spouse's family. I made several attempts but often stopped due to stress. In 2024, upon hearing that my mother-in-law plans to visit us, I started studying seriously. I set a goal to quickly learn all the content from August to November 2024 using the TTMIK Story App. I read for 2-3 hours a day and looked up unfamiliar words myself. Additionally, I utilized Cho Soo-soo's podcasts and YouTube content to learn in an understandable input method. Through this experience, I am curious about how beginners in Korean can transition to intermediate level. I would appreciate advice on how others have learned.
