Bilingual people might have an advantage over monolinguals, but motivation is still the most important reason for one to succeed. I grew up bilingually, had French for five years in school and and hardly ever managed to formulate a proper French sentence (honstly, I was one of the worst students in my class). Reason could be that I'm not interested in France. I actually strongly disliked everything French back then, now I regret that I never learnt French properly) I studied Latin in Highschool because it sounded like a language that educated people should know. I never understood Latin. When I took up Japanese classes things seemed to repeat. I couldn't understand anything, the only thing I learnt were the Hiragana and Katakana. I quit.
But I continued my Japanese studies thanks to Pimsleur. I completed the first Pimsleur lesson and realized that I was able to speak Japanese even though I didn't really understand anything (grammarwise). I continued my studies and today I watch Japanese TV-Dramas without the help of subtitles, talk with Japanese people in Japanese and I'm currently working myself forward to literacy in Japanese after RTK1. What has changed in these years is the attitude I have towards foreign languages. I now believe that I can learn any language I want (will tackle French soon). And I don't care if there's something I can't understand grammarwise. If encounter things often enough, repeat the texts over and over, I will slowly come to understand everything about these foreign languages.
