I'm learning because I am a teacher and I would like my younger students to have an exposure to another language and culture as early as possible. I will share what I learn with them. The town where I live is not multi-cultural, so this is their only opportunity when they are young to experience and enjoy other cultures. So, maybe I am learning for the sake of world peace; at least that's what I like to think. :-)
