Anywhere you live in the US (short of New England, I assume) Spanish will get you a long way. Florida has been "essentially spanish" since its discovery.
Once you learn Spanish, Italian and Portuguese are little more than a fancy holiday read
.
All three languages provide tons of interesting, amusing, fun literature.
Also, these three languages evolved into their modern form centuries before English, so that reading a novel in the "original 1680 text" is actually quite simple.
French is also related, but grammar and pronounciation are much more sophisticated (= unnecessarily tweaky
)
Moreover, Victor Hugo's "Les Miserables" will enlighten you no better than Charles Dickens' novels...
PS If you want to study Spanish, please be aware that true Spanish is called "Castellano" and that pronounciation is a bit more sophisticated than tex-mex "Chicano"
Claro che si !!!
