I currently live in Korea and have learned a little bit of the language. It is usually one of the hardest languages for English speakers to learn, but it is also worth it if you're willing to put in the time and effort! I have only met a few Americans who speak fluent Korean and I was really impressed. So the bottom line is this: yes it is very difficult, but it can also be very rewarding. And if you enjoy learning languages then it will be fun! Hope this helps.
