Sometimes having a desk job isn't so bad, one time (quite recently) my job was watching Buffy all day.

Remember - dreams do come true. Find something you are good at, and go with it. One day it will come in handy. Work on it. You will find a use for it. Trust me on this. My secret power is that I can identify an episode of Buffy within 4 seconds of it starting, and I got to use it in my real life day job. Unbelievable.
