It's a lot harder to keep your cool than it is to lose it. That's on any work ethic. Even if you're a big producer on a movie set, or whatever, it's a lot harder to be a pro than be a baby on your crew. That's one work ethic to keep in mind, as one bad apple could give five people a bad day, when that one person could've stepped up their own efforts a little more and not bring anyone else down.
