>>24560425I am too lazy to structure my thoughts here but
1. it's best to as quickly as possible reach the level where there is some activity that you can do in your target language even when you're tired and stressed, before you reach that level inputting will be very tiresome and that's the riskiest time in terms of quitting. That's why I recommend dedicating at least 1 hour a day to French
2. reaching the level where you can comfortably read some authors in French doesn't take that long, it can be as short as 6 months if you're really dedicated. After that you'll just continue to read and improve, eventually being able to comfortably read more difficult authors, even authors who made you feel like you didn't know French at all when you last tried to read them.
3. please just stick to French, don't get distracted with other languages
4. Yes you should start studying today
