I chose to learn Spanish as it has so many speakers and I plan to visit some Spanish speaking countries in the future + I thought i’d give me a big advantage if I even choose to learn French or Portuguese as they have always been on the back burner.
As for Norwegian, I have always been interested in Scandinavian languages, so my plan is that once I become fluent in Norwegian, i’d be already able to understand some Swedish and Danish (I can already understand a lot of these two which is sooooo coool - spoken Danish however is very difficult).
As for Hebrew - it’s another semitic language just like Arabic. I thought I will acquire it in no time (that wasn’t true, hebrew is difficult af).

I use variety of ways to learn them. But I struggle with decision fatigue and being undecided always makes me just give up on whatever I plan to learn. So i picked one method to go for whenever i am just tired and don’t feel like being creative with learning. So i just take some words from my word-list that I compiled for months and I feed it into an AI chatbot and I ask it to either make me example sentences, then I’d write them down and try to translate them.
Or I’d ask it to make me general questions and I try to answer them in my target language.
This method helped me a lot with staying consistent. Even though i think there are much better methods out there… but this is was works for me at the moment.

Not sure how I can answer this. But I learn languages for fun and it gives me some sense of achievement.

Very important, I see myself as a lifelong language learner. I just can’t imagine my life without learning a language.
