Personally, I suggest you study Nahuatl.
If you learn Chinese, you might as well go learn Japanese at the same time. It makes every vastly easier. If you aren't necessarily that good at learning languages, then doing them at the same time might not be advisable, but learning one makes learning the other incredibly easier. Also, Chinese is really, really nice for an employment standpoint, as Icewalker pointed out. And China/Japan has some amazing food.
