How to become a polyglot?

A polyglot is a person who speaks or understands many languages.
After I've learned English, I feel like I would like to become a polyglot. Sometimes, I am really surprised that there are many people who are polyglots in the world, and I realize that I want to be like just like those that person people. Unfortunately, at this time, I can only speak Korean and English, but I want to speak 1 or 2 more languages. I don't know why I would like  want to be a polyglot, but I just want would like to be. While I am learning English, I have noticed within myself that I really enjoy making a process, such as to expand my vocabulary, and feel rhythm, and make a new English speaking friends and so on. Likewise, I think I can get many advantages if I can speak other many foreign languages. I don't know how long it will take to speak other languages, however I assume that it might take more than a 1 year to communicate with native speakers. of target language. The most attractive languages for me are Spanish and Japanese. I like listening to Spanish conversations. It sounds sexy. I also have a few Spanish friends. They are very friendly. So, I think I can learn many things from them If I ask something questions from them.
Japanese and Korean have many things in common. Some vocabulary are exactly the same and I have heard that the grammar rules are is very similar. Furthermore Finally, I have learned Japanese when I was in middle school as a student, but I have totally forgotten it. What a shame...

Anyway, I believe that where there is a will, then there is a way. Learning a language is one of the most my favorite my hobbies. I imagine myself as someone who can speak many languages!

Well done!
