I'm just new living in German. How the best way to learn it?

Answer 1

You mean learning German?

Go to classes, ask people around you to speak German with you, start reading German as soon as you can understand it, anything will do, reading things you enjoy do better.

The most important thing is not to be afraid to make a fool of yourself a few times now, otherwise you will keep making a fool of yourself for as long as you live there.
