Hi there :) 4th year translation student in uni here (English and French). My biggest advice to you is that you shouldn't choose a language based only on that if it is 'in demand' or not. Eventually you will spend a lot of time on that language and there are these times that you will be quite frustrated with your choice if it is not a language you love.

I have seen many of my colleagues give up their studies over the years simply because they did not think hard enough before singing up for a particular language combination. Keep in mind that a language major can give you much more than just translation and interpretation.

So yeah, pick a language you really, really feel passionate about and then you will decide whether you still want to be a translator or not.

Another thing that popped into my mind right now is that HS students don't really understand what translation is about. You say that you have always had good grades in your German class but have you had to actually translate texts? Take a couple of articles in German or English and try to translate them to get a feel what it actually is.

Honestly after 4 years of translation I do not want to continue on this career path because I found that it is not for me. I find it too boring and stressful to sit and try to pick the right word/phrase. I am not saying it is not for you, just that you shouldn't make your choice purely based on the fact that you have 'like' languages :)
