What I love the most in the world is learning languages.
While I do like to learn computer languages, learning natural (that is, normal) languages gives me even a greater joy. I don't think I am a good writer, but manipulating letters and lingual sounds is such fun. I love learning grammar, too.
I wish I could make money just from learning languages. Probably, I should develop some websites or software that help people learn languages with pleasure. That could be the purpose of my life.
