It's going to be rough working in English all day, then trying to learn German in the evening, especially if most people interested in talking to you are those who want to practice their English.

It's tough to find people willing to talk with an adult like they're a toddler.

So, I don't think the question is as flippant as you made it out to be. Someone might have some real advice about how to manage the juggling act of learning a new language and culture as a working adult.

That's the trap of working in industry lingua franca of which is your mother tongue. Otherwise public libraries in Germany are very well equipped and have wide selection of audio content - language curses, audiobooks, some might find it more helpful than just grammar handbooks.
