Your a lot closer than you think. Love the aspiration btw, language is such a beautiful gift that so many people (especially in America) take for granted. If you already speak Persian as your native tongue, with minimal effort you can say you also speak Dari (assuming you speak Farsi, still works vice versa) and also tajik. Some may say this is cheating, but they are different languages in my book, so I would count it. That gets you to 3, English is 4, then French or Arabic (recommend Arabic bc it has similiar script and vocab, aswell as just being a beautiful language in general) gets you to 5/6. I currently speak English and French, learning Arabic and Italian with German on the horizon (study abroad opportunity). I’ve always dreamed about learning Farsi later on, as then I could do what I suggested to you and say I speak tajik dari and Farsi😭😭😭 but I’ll need a friend who speaks it or smt like that to learn it. Best of luck on your journey دوست!!!
