Being a macho, tough guy is overrated. At one point, I actually thought that was the only way to battle my SA... it might seem weird to you, but in either case, I came to the conclusion that I'm a nerd. And for some reason, I've felt like a burden's been lifted ever since.
Al I'm saying is, trying to act tough can only do you harm. Most likely, someone's gonna kick your ass down to size (lol). But if you want to be tough, start lifting weights, gulp down huge protein shakes and enjoy your new way of life. Or, you can just be yourself... just a thought... 8)
