Even though it perhaps caused you problems when you were little and your parents tried to teach you two languages at the same time, right now when you are able to speak both at a very good level you can see that the hard work was worth it. Because not only you have it easier at school when you need to study a foreign language, but it is also a very valuable skill in your everyday life! Ain´t that right?
And speaking foreign language is always incredibly sexy too! And it does not really matter what you are saying. Everything sounds so exotic! Plus, it is a great thing for your CV. And also, the opportunities for a part-time job as a language teacher are always open to you!
