What's the hardest part of learning Korean for you right now?

I'm still learning Korean, and I've realized that the hardest part changes as you progress.

At first, Hangul felt difficult to me. Then vocabulary became harder because there are so many words to remember. Now I sometimes find grammar and remembering when to use certain expressions challenging too. 😭

I'm curious about other Korean learners:

What's the hardest part of learning Korean for you right now?

Is it vocabulary, grammar, pronunciation, listening, speaking, or something else?

I'd love to know what other learners struggle with and how you're dealing with it!
