Sometimes you got to suffer a little in your youth to motivate you to
succeed later in life. Do you think if Bill Gates got laid in high
school, do you think there'd be a Microsoft? Of course not. You gotta
spend a lot of time stuffin your own locker with your underwear wedged
up your arse before you think "I'm gona take over the world with
computers! You'll see I'll show them."
