What would you save from Earth?

I once had a dream where the Earth was collapsing and we all had to hurry to get on a rocket ship to take us to another planet. There wasn't very much space on the ship, so we each could only bring 5 things (not including people or animals) with us. I remember choosing Beethoven's music, but I don't remember the other 4 things.

I often think about that dream and try to decide what I would choose now. Beethoven's music still makes the cut! What 5 things would you bring?
