The extent of my german language abilities

So, I have now mastered the numbers from 1-100, and various greetings (hi, good morning, cheers, bless you, goodbye, etc.). However, every time I actually need to use German, it usually involves asking for directions. And if people respond to me in German, I have no clue what they're saying. Therefore, I'm pretty sure that my time would have been better spent on practicing miming skills...
