Learning a foreign language is so much fun, and seeing your enjoyment...how can one not feel happy! But, if you want to be a linguist for instance (maybe this is not your interest, but if you do want to be one) you need to specialize and dig deeper into a language (its historical development for instance or its literature). I am sure that whatever you choose, you will be good at it. Good luck!
