The Challenges of Learning Korean and the Joy of Learning Numbers

I recently started studying Korean again and I'm struggling with sentence structure. I'm somewhat familiar with words and vocabulary, but using the appropriate particles in sentences is particularly challenging for me. This aspect feels like a significant obstacle. On the other hand, converting numbers into Sino-Korean feels like putting together a puzzle, which is very enjoyable. It's a long and complex process, but the process itself brings me joy. I'm not completely familiar with the counters yet, but I feel like I'm improving gradually. Do you have any tips for making sentence structure easier to learn or for remembering particles better? Your advice would be greatly appreciated!
