I enjoyed my little stint at Career Night. One of the kids reminded me of a younger version of myself. He had made his own pen and paper RPG, liked to do "world-building," and had lots of unfinished comics in his binders (I guess we vary on that point; I drew a lot of figures but rarely actually created legitimate comics).
For the most part, I think they wanted to mine me for something interesting they could take back to their friends. That is, if I could tell them something top secret about the next Call of Duty, or if I had worked on something mind-blowing that the whole world loves.
The most surprising thing was how well their attention was held when I, on a whim, decided to walk them through some pretty dense design theory. I walked them through some shortcomings I see in multiplayer games and a different way to approach multiplayer experiences, and they actually seemed to be fairly engaged through the whole process. Go passion.
That was the only real "life advice" I tried to give. "Do things that drive your passion. Even if you end up in a dumpster, you'll be happy doing something that fills your soul." I should stay away from the dumpster advice next time, maybe.
