Well, you're into art, right? Something like that is a pretty broad topic that you can do a lot with. Or it could be something more abstract, like "what I was thinking about when I woke up this morning" or "things I would tell a person who had just been asleep for 1,000 years about modern society."
I want there to be some variety since I can't seem to stick to one topic. I have a few ideas in mind, though.
