Everybody has to start somewhere. You have your whole future ahead of you. Perfection doesn't happen right away.

Let your body work until it is spent, but keep your mind for yourself.

One other thing I learned from working in a company was that the majority of people in the world have no problem following orders. They're actually happy to be told what to do. They might complain, but that's not how they really feel. They just grumble out of habit. If you told them to think for themselves, and make their own decisions and take responsibility for them, they'd be clueless.
