If you’re trying to choose which language to learn, the following question, which is based on one I came across yesterday, might help you to decide:
If you were offered a free trip to one of the countries where the languages you’re considering are spoken, which country would you choose?
For me, choosing which language(s) to learn is a frequent conundrum, though often the choice is between learning a new language, or brushing up and improving my knowledge of
languages I already know. Often I end up trying to do both.
