As an educator with a teaching career (ESL) that has spanned over 28 years now, and as someone who learned the Portuguese language at the age of 51 before coming to Brazil over 13 years ago; I can tell you that everyone here is correct when they say that immersion is the only way to go. I created my own near immersion in the language before coming here and it put me lightyears ahead of where I would have been had I not done so.
Any exposure to the French language in both its written and spoken form will aid in your growing process. Find French language news articles, magazines and texts online. Listen to French language music and watch movies on DVD with audio in French only and no subtitles the first viewing, watch again with both audio and subtitles in French to catch what you missed. Find the French community where you live and become a part of it, make new friends within that community. You'll find your language skills will improve by leaps and bounds.
