Study in Berlin?

I received an email from a Berlin University informing me that my application for a Master Study in International and Development Economics has been approved. This seems to be a turning point of my professional life, or I don't know. For sure, I will have to leave my job at the Tax Department in Jakarta, at least for the next two years started in March. Well, there're still a lot to be arranged before I depart for Berlin in spring 2008. So, I wish myself a good luck ... :)
