How did you guys learn other languages? I took Spanish in high school, as well as middle. I understand the language andhave decent vocabulary, but I wanna get better understanding before I jump into Japanese. What say you guys?

A shit ton of books and complete relinquishment of my social life. I study my target language whenever I have free time, in addition to listening to music in the target language, speaking along with recordings and using learning software like Duolingo (highly recommend Duolingo btw; sadly it won't do you much good in japanese at the moment).
