ping la Posted 10 months ago How many languages should we learn in bussiness? which one we must have to learn? Really thanks for your comment. From telling me language history to how to choose languages by myself. Really useful. I'm still learning for french now. I'm interesting for it but i don't know did I make wrong choose? Maybe I should choose more helpful languages first instead of french? (ex:Spanish,Portuguese ,Japanese...etc) Will you change your mind to give up French?
