Yo Nerd - On something like this, it's all out friggin' war - envision the knife fight scene in Saving Private Ryan when Mellish is fighting for his life hand to hand with that German. Eye gouging, finger biting, choking, screaming fight for your life. THAT's how hard you have to fight for this. If you truly want it, start right now, go to a place where no-one can find you. Take a loaf of bread, a jar of peanut butter, a six-pack of cokes and study until the sun goes down - then study more. Then study more. Then study even more. Don't study with anyone else - F them - it's your future on the line. You gotta want it so bad it friggin hurts you to the core. If you want it that bad, then you will make it.
Do you want it that bad? Are you willing to fight that hard?
