Those are mutually exclusive, unless you aim for speaking French after you're ninety. The truth is, either you get the work done, or it isn't getting any doner. The best way to go is immersion. Move to France; if not possible, find as many French books, newspapers, podcasts and songs as you can lay hands on and start reading and listening (just to get some grasp on verbal syntax - your subconscious will do it for you for now, just read and listen), find people who speak French and would like to learn Swedish (there are some resources online for that: /r/languageexchange on Reddit and GoVoluble) and speak French with them everyday, no matter how broken it is and how stupid it feels. In a year or two, if university programs are any indication, you'd be able to communicate more or less freely.and I do it on duolingo when I get the urge but I would really like to speak french fluently.
