about learning Korean

My language is South Korean. I think it's lucky for me because learning South Korean is really hard, but I automatically know how to speak and understand Korean. However, I do not know how to speak standard Korean because I just learned special Korean that is only used in my city . So even me, a Korean, has problems with using Korean. Sometimes, my friends from Seoul and I have trouble to understand each other. But I do not have problems to write essays in Korean because it's all same for Koreans to write. Koreans is really hard to learn. It's too hard to speak and make a sentence because we have special grammar. Maybe learning English is better way to learn a language.
