I think German is hard to learn because of the different gender.
Even People who speak a VERY good German tend to make mistakes when using"der / die / das" or the differnt causes (Nominativ, Genitiv, Dativ, Akkusativ)
((Boy and Girls, be happy that you don't learn Latin or Greek !!!))
Demo, alle anwesenden Nicht-Deutschen sprechen sehr gutes Deutsch.
So I think I speak for all Germans here that I am (somewhat) proud that you learn German an if you have any problems don't hesitate to ask!
