IT’S NOT SO BAD
First of all, let’s cut the bullshit. Getting fucked up really bad isn’t that bad. Thanks to the anesthetizing tendencies of adrenaline it’s not even that painful.

When someone says, “I am going to fucking kill you,” think of it more as “I am going to audit you,” because all he’s really doing is adding a huge mundane thing to deal with into your next 24 hours. The truth is, the three-week-long pain of regretting that you pussied out is a hell of a lot worse than the dull nonpain of getting in a fight, so there’s no need to be scared. And hey, if you’re that calm you might even win.
