Let's see.... I remember seeing Robotech and Astro Boy when I was really little. Later it was the Sailor Moon/Dragonball Z that solidified my otaku-ness. I kept myself away from anime outside of television because I couldn't afford it, but once I got a job I started slowly collecting.
I still think my collection is small. Three shelves of manga, working on the seventh shelf of anime plus the stuff in my nightstand *wink*. I'm not in denial, for you can never have too much anime!!
