How about your experiences as an anime fan before the show, how it was handling schedules, crew, etc., and how you balance your post-life with your continuing love for anime?
You could talk about how you experienced what is largely considered a "normal" life (if you feel that), and any negativity you felt when confronting this with your "otaku" side. Also, what your future plans might be.
I don't know about other people, but when I was younger, I had a worry about my anime love and the "real" world and if I could balance the two or not. I remember thinking when I was 13, "Will I still like Sailor Moon when I'm 16?" and when I was 16, "Will I still like anime when I'm 21?" Other people might be having similar worries, and your experiences could provide comfort for that.
For the record, I'm 22 now
