Sometimes I don't kill people . . .
Sometimes I don't think of ways to blow up buildings . . .
What matters is not SOMETIMES. What matters is what you do consistently. Believe me, you spend a semester using your brain only sometimes, and you'll find yourself with a shit GPA and no chance of catching up. Life likes to fuck up stupid teenagers who like the concept of only thinking "sometimes".
Here's a hint. Hit the ON switch on your brain, and leave it the fuck alone.
Preview Edit: You TRY?!? If this is your best effort you must have the education of a retarded blowfish. For fuck's sake man, it's not THAT hard.
