I speak Romanian (native language), English and now I'm learning spanish by myself. After I am fluent in spanish I will try to learn korean. In university, if I get in the one I want, I will learn chinese. I want to make a career out of foreign languages and i love learning new languages.
I also can understand Italian and can make a conversation. Same with german but not as good since I'm not learning it anymore in high school.
Spanish it's a easy language to learn since Romanian and spanish are very alike. Same goes with Italian. But this is what i do: I bought a book called "learn spanish without a teacher". It has lessons, exercises, texts to read and translate. Also duolingo is a great app and it's the most useful for me. Try to find native speakers you can talk to. I have a friend that is from Spain and she helps me a lot with words i am not sure about. This way I can practice my pronunciation too.
I wish you good luck. It's a beautiful thing to know other languages.
