Every kid sitting at school bored in class gets to work and envision performing on stages with the rhymes they write. Me included, but as a student of Nas since 2003 in seventh grade even I could hear an upcoming rapper such as Lupe Fiasco in 05-06 and basically have my dreams laid to rest, because I know I could never in my wildest dreams do what Lupe could do with words.
But Lupe can catch that same holy ghost from one of his heroes and it has the opposite effect. It inspires him. That's what makes these guys' brains different than ours.
