As it turns out, Shia has no idea what his job is all about. In fact, he doesn't have a clue how to act. Hmmm, where can I spend money on a ticket for that new Transformers thingy?

"I don't even really know what it is I do for a living - the level of insecurity is very, very high. You're making a lot of money, getting a lot of accolades and positive criticism for something where you don't even know what you're doing. There's no business model for this. You can't go home and say, 'You did your job today', because I don't know what my job is! That gets crazy, trying to figure that s**t out… Actors are dependent on being validated by other people's opinions. I don't understand what it is I do that people want. I don't know what an actor does. I have no credentials. I don't know what I'm doing. To my mind, talent doesn't really exist. Talent is like a card player's luck. It is motivation, ambition, and luck. I think acting is a con game."

Yeah, how you're a big deal is, and will probably forever be, a complete mystery.
