Why learning English?

Today I was having a chat with one of my clients over the skype and was not able to understand his language properly because he was taking in an American accent, and I was taking in my Indian accent. It is not that i don't know English or my client doesn't know English, but it was just because of our accents that we were not able to understand each other. So after that call I searched for the solution of this problem and found this website. and I believe i can have enough friends from other countries so that I can chat with them and try to correct my language and accent.
