     Is learning a foreign language ever easy? Yes. If you are five and move to another country, you will

quickly pick up the language. But what about for the rest of us who are no longer five, and need to be

polite when traveling for business or for pleasure? I think that answer is also yes. Language learning can

be easy if you don't want or need to learn too much. 

    The key to successful language learning in my mind is not to set the goal too high. It is rather like

running. Even if you run twice a week, you don't necessarily want to be able to run a marathon. You

might just want to maintain a level of fitness. I think the same can be true for language learning.

     Let's get back to the goal. If you decide to learn ten words in a foreign language before visiting the

country, you know that you will manage to do this. However, if you decide to attain conversational

fluency, unless you are an exceptionally talented individual, you will probably fail and give up in disgust.

     It is also far easier to start learning a foreign language than to finish. In other words, the better you

are, the slower it can be to improve, because you will get stuck with grammar, making sentences,

learning less common words, etc. If you are only trying to learn a few foreign words and phrases, you

will enjoy faster progress, have more fun, and won't have to spend too much time. 

    The idea of learning only a few hundred words in a language, and then stopping, isn't the usual

approach to language learning, but it can be a very rewarding and entertaining activity.
