Your artistic abilities are limited to lopsided stickmen. You can't program your VCR, let alone an animation compression system. You are too busy trying not to miss the expiration date on your milk to schedule project milestones. When you try to play Chopsticks on the piano, you get soy sauce on the keys. In fact, you have no marketable skills whatsoever, but you still want to break into game development. You want to be a Designer.
Funny, somehow I think Bungie is about to see an increase rather than a decrease in job applications. Check the article out, it's a very worthwhile read.
