I'd like to live in Germany. I've just started learning German. Give me any tips about Germans and German culture/language.

I'm a teenager from a EU-country. I'd like to study college and maybe live in Hamburg, Germany. I'd like to have any tips to start preparing to live there and to know more about Germany. Also, any language tips would be cool! I use Deutsche Welle page to learn German (Duolingo is nice, but I don't like to give my e-mail to anyone in general).

Any tips you can give me? Thanks in advance!
