What helped you the most when learning Korean?

What do you think has been the most helpful to you while learning Korean?

For me, a lot of things have been helpful such as having Korean friends to practice with (or dating with a native speaker), or having lived in Korea (I did this too), as well as practicing speaking in general, or watching dramas and listening to music, and many other things.

I talked with my friend Andy, who's also a fluent Korean speaker, about what we felt have been the most helpful things in our Korean learning journey to bring us to where we are now.
