From reading so many posts English seems to be a generally accepted language, and you are educated in English as well as German.
German, because this language itself contains long words and needs a lot of memorization.
My daughter chose German as a third language in her sixth grade and found it very difficult and boring to learn the language, however, she learned some pronunciation vocabulary by watching German speakers on YouTube.
Yes absolutely right, like any other foreign language, not easy. Especially with those separable verbs (what fun!). Take a look at Deutsche Welle on the web. A very good starting point.
