90% mental playboy. Just keep in mind that whatever they do or say, it's only their job. You gonna see and hear some shit you have never been exposed to before, but keep your head up and stay mentaly focused. Don't be afraid to reach down till you have nothing left. You will break, everyone does. But once you get passed that it's all down hill. Shit, I could talk to you about boot camp all day long (got a million stories to tell).
