How do YOU use astronomy in everyday life?
Or do you at all? Observing the sky and compiling meticulous records of the events was vital in ancient cultures (as you will find out on the lectures). The sky you see is the same sky the ancient peoples saw; the human psyche is pretty much the same now as it was then.
Try to think of ways how celestial events affect your life, and write them down (we will discuss these at the lecture). You can keep it simple, no rocket science (necessarily) required here.
