I've learned a couple of languages as an adult and the experience is nothing at all like learning a programming language. The road to fluency in an acquired tongue is extremely mentally taxing. You end up having quite a lot of deep, meditative thoughts sessions about the structure and usage of the language. The first few days spent immersed (i.e. speaking it all day long) can be exhausting. I've never experienced anything while learning a computer language that comes close. I guess the closest analog I could think of would be switching cold turkey from procedural to functional programming, or something. P.S. Choose Spanish. Waay easier than German, and of course Japanese is among the hardest languages for native English speakers to acquire.
