Marcus Arelius (yes, the one from Gladiator) in his writings 'the Meditations.'
Marcus wrote a lot about the flow of thoughts and

MAN: "Yo dude, what's up?"
DUDE: "
Nothing, I was just wondering why you weren't being TOTALLY EXTREME like I am today, with my cool anti-

DUDE: "Yeah, I know what you
mean, man."
