A hilarious way of making a simple point: don't try so god damn hard to be something you're not
. Desperately pretending you're super educated, worldly, the coolest guy around, rich, a great snowboarder or a barnyard animal does not necessarily make it so. Not only that, it will likely cause you to look incredibly stupid in the process.
I credit this line to The Fight Club
, although I'm not sure these are the exact words Brad Pitt used.
