What I learned most was how to tell a story in 15 seconds or 30 seconds or 60 seconds - to have some kind of goal of what to try to do and make it happen in that time.
I grew up in the '80s where there's a lot of these kind of post-apocalyptic, post-comet, post-whatever it was, so that always captured my imagination a lot as a little kid, that idea of getting access to secret places and being able to roam around where you're not supposed to.
