Three years ago, I've written something very similar but instead of "Germany" it was "Californie". I bought the same book "english for dummies" haha. I was so stressed out. It actually helped me a lot so, I've decided to follow the same path and buy "german for dummies".
In 5 days, I'm going to work in Germany where my mom used to do a part time job when she was in college. I don't know what I'm going to do or with who I'm going to work but I'm very excited to learn and experience a new culture. Learning the hard way is the best way to improve!
I'll made a post with more details later. Auf wiedersehen!
