Be an amateur ethnographer and you'll have a lot of fun and learn a lot. Make plenty of small mistakes. Also, forgive yourself your mistakes as soon as you make them. Don't ever fall into the trap of thinking that making a mistake in a new culture or location means you are not capable. If you are not making any mistakes, you are probably not being adventurous enough.
Mistakes make wonderful opportunities for learning.
Once, shortly after I had arrived in Germany for the first time, and before my German was adequate to the tasks at hand, I went for a long walk around the streets of Munchen. However, I had written down the name of the street where I began my walk. I stopped a friendly-looking face and asked if he could tell me how to get back to the street I was looking for. The stranger was very helpful. We took out my map, found where I was, and figured out together where I needed to go.
