Need counsel: How hard are Greek/French/Thai/Italian for a student minoring in Spanish?

okay so with french, thepronouncing will get better when u take the class because u wil learn the rules of it. French is spoken in alot of different reigons throughout europe and parts of africa. And ive heard thai is REALLY hard to learn, but if ur gma speaks it then i think it would be good to learn how to communicate with her.... hahaha Greek would be helpful if ur going into a medical feild cuz alot of medicine has gree roots. so do alot of words in english. Its still pretty hard, but probably not as hard as thai. And i really want to learn italian too, and it isnt uselful unles u want to work for the embassy or something. Italian has alot of similar words to spanish, i speak spanish and i have done a little online learning of italian
