When I was child, I have a dream to master 5 languages. they are sundanese, indonesian, english, arabic, and japanese. today, I just have mastered 2 of them, sundanese and indonesian. I think, I 'm in the right community now to master others languages. Mastering foreign language is very important today. language, as a protocol for computer, can make us communicate each other. there are a lot of knowledge and wisdom in the world. language is a tool for share it.
