How do you feel when you\'re able to communicate with an English speaker?

When I talk to someone in English, I feel good. Learning English can help me a lot. such like when you travel abroad, share your culture with foreigners. making friends. However, I often having a difficult time. Because I\'m still not good at speaking I can speak English slowly. It takes a long time to think. For example, why do you think so? When asked me, I only talk about the conclusion. just I like it! That\'s why. My problem is that I can\'t explain. I think I am not good at explaining Korean either. In fact, I think lack of the skills to make sentences. therefore I will try. I want to improve my speaking skills through English classes.
